Choosing the right path for your career in Web Development

Technology plays a major role in our daily lives, from simple applications to highly innovative products. Every website or piece of software we come across is designed by a web developer — but before move on you might have a question in your mind that what the hack is web development, and what is a role or work of a web developer?

To the naked eye, it may seem like a complicated, confusing, and inaccessible field. So, to enlighten you on this exciting industry, we’ve included a final introduction to web development and what it takes to be a fully functional web builder.

In this guide, we will take a closer look at the basics of web development, and show you the key skills and tools you will need to enter this field.

First, however, we will look at the web development industry as it stands in 2021, and then look at whether web development is a smart career move — with a strong focus on the impact of 2020 and the COVID-19 epidemic.

1. Is now a good time (beginning of 2021) to become a web developer?

Before embarking on a new career, it is important to look ahead. Can your new industry give you enough opportunity and stability? How likely are you to be hired after your chosen program or bootcamp?

In the wake of 2020, these questions are even more important than ever. The COVID-19 epidemic has had a profound impact on the economy and the labor market, with employment declining in many sectors. With that in mind, let’s take a look at the state of the web development industry by the year 2021.

Web developers are in demand right now?

You will realize that, no matter what happens in the world around us, technology is everywhere in our lives. Whether it’s scrolling to our favorite social networking sites, watching the news, paying for something online, or communicating with partners using software and collaboration tools — much of what we do depends on a particular type of technology. Behind this technology is a team of web developers who not only built it but always maintained it to ensure it works flawlessly.

Those who can build and maintain websites, apps, and software have a very important role to play in today’s technologically driven world — and this is reflected in the web development job market. According to the Bureau of Labor Statistics, hiring web developers is expected to grow 8% from 2019 to 2029 — much faster than the average of all jobs.

But is this still behind the unexpected changes of 2020? In short, yes; Web developers seem to have withstood the storm well. Just search the web to find much-needed tech skills by 2021 and you’ll find things like web development, cloud computing, DevOps, and troubleshooting.

Complete development will continue to attract more employers. Writing to TechCrunch, Sergio Granada comments on how developers of full stakes became part of the business during the COVID-19 disaster: “By responding to the coronavirus epidemic, the potential for full development could enable engineers to sell more like companies in all industries and move their business. Those who can quickly develop and deliver software projects due to overcrowding can be shot at the top of the company or customer wish list. ”

If you wish to measure the need for web developers, search for the roles of “web developers” or “full builders” in your area on sites such as glass, glassdoor, and LinkedIn. We quickly searched for web development roles in the United States and, at the time of writing, found more than 26,000 posts.

As you can see, web developers continue to be in high demand — albeit, perhaps even more so due to the ongoing coronavirus infection. Talk about it; How has COVID-19 affected the web development industry? Let’s take a look.

How has COVID-19 affected the web industry?

While many industries have struggled (and continue to do so) as a result of the coronavirus epidemic, the technology industry has come a long way. Many organizations rely on digital tools to operate remotely, placing greater emphasis on technology and the people who build it. Thus, many expect a sector explosion; according to Market Data Forecast, the technology industry will grow from $ 131 billion USD by 2020 to $ 295 billion by 2025.

Yes, freshers can expect some changes as a result of Coronavirus. First and foremost, it is important to look at long-term job growth. When it comes to looking for your first job within the industry, you should be prepared to work remotely at least some of the time, if not fully. Fortunately, web development is a long-term job loan. You can learn more about what it is like to work as a long-distance engineer in this guide.

We also expect that web developer jobs will increase in certain areas as a direct result of the much-needed products and services now. For example, sectors such as health care, media and entertainment, online banking, distance education, and e-commerce will continue to grow reflecting consumer needs and behavior in a far-flung social world.

Overall, the impact of COVID-19 on the technology industry, and web engineers, has been small compared to other sectors. While the situation continues, new and aspiring web developers may feel confident that they are embarking on a future-proofing project. If you want to know what it’s like to be a recent graduate of technology in the middle of the epidemic, see our guide to job search during COVID-19. In it, Mike McCulloch, Head of Career Services at CareerFoundry, shared his insights into the technology career market, as well as great tips on how to market yourself as a newcomer to the field.

Should you become a web developer in 2021?

Now, what is the decision? is it a good time to be a developer?

When we look at the job market and the expected growth in speculation, we think the answer is very clear. Now it’s a good time to be a NiNJA! Now more than ever, technology is critical to our performance, communication with our loved ones, access to health care, shopping… and the list goes on. If you are thinking of joining this exciting industry and building the technology of the future, we say it works for you.

But first, let’s get back to basics. What exactly is web development, and what does a web developer actually do? Keep reading to find out.

2. What is web development?

Developers who are building a web (websites, web apps) and that process to make a final product is called Web development. That might be an open in-network or intranet product. Web development does include web design, it is also about programming that transforms design to a dynamic site.

From the simplest, most consistent web pages to social media and apps, from eCommerce websites to content management systems (CMS); all the tools we use online every day are built by web developers.

Let’s look more at web-development.


Client-side means UI/UX. In short, what we see while surfing a website is called a client-side. It includes design, layouts, fonts, colors, etc


Server-side is also known as backend development. The backend includes mainly business logic, database architecture, and APIs. Basically, user input will be sent to the backend for further calculation

Database technology

Websites also rely on database technology technology. The database has all the data and content needed for the client-side to work, to store it in a good manner that it can be fetched update and modify easily. The database works on a server, and most websites use some form of relational database management system (RDBMS).

Summary: frontend, backend and database technology all work together to build and operate a fully functional website or application, and these three layers form the basis of web development.

What’s the difference between web development and web design?

You may have heard that the principles of web development and web design are used differently, but these are two very different things.

Imagine a web designer and a web engineer working together to build a car: the engineer will take care of all the working things, such as the engine, wheels, and gears, while the designer will be responsible for both visuals — car look, dashboard design, seats — and user experience provided by the car, so — then the drive is smooth or not.

Web designers are designing what a website looks like and feels like. They mimic website design, making sure it makes sense, is practical and fun to use. They look at all the different visual effects: what color schemes and fonts will be used? What buttons, drop-down menus, and scrollbars should be installed, and where? What contact points does the user interact with from point A to point B? Web Design also considers the design of a website, determining what content to include and where it should be placed.

Web Design is a very broad field, and will often be divided into specific categories such as User Experience Design, User Interface Design, and Information Architecture.

It is the job of the web developer to take this design and develop it into a live, fully functional website. The previous developer takes the visual structure as given to the web designer and builds it using encoding languages ​​such as HTML, CSS, and JavaScript. A backend developer builds more advanced site performance, such as job evaluation on an e-commerce site.

In short, a web designer is a builder, and a web designer is a builder or an engineer.

3. A history of the World Wide Web(WWW)

The web as we know it today has been done for decades. To help us understand how web development works, let’s go back to where it all started and consider how the internet has changed over the years.

4. What does a web developer do?

The role of a web developer to build and maintain websites. Web developers can work internally or internally, and the specific tasks and responsibilities involved will vary depending on whether they work as a frontend, backend, or full-stack developer. Full-stack developers specialize in front and rear; we will go into more detail on what the stack builder did in full later.

Web developers are responsible for creating a product that meets both client and customer or end-user needs. A large part of web development also focuses on bug detection and bug fixing so that it can always work and improve a website or system. Web developers are therefore their favorite problem solvers, always coming up with solutions and functionality to keep things running smoothly.

After all, all web developers are skilled in certain programming languages. However, different engineers will work in different languages ​​depending on their job title and field of expertise. Let’s take a look at the different levels of web development and related functions in detail.

Role of a frontend developer

It is the job of the frontend developer to insert the front code of a website or application; that is, the part of the website that the user sees and shares with them. They take the background information and transform it into something that is easily understood, fun, and fully functional for the everyday user. They will work from projects provided by the web designer and make them live using HTML, JavaScript, and CSS (more on that later!).

The frontend developer uses website design, interactive, and navigation features such as buttons and scrollbars, images, content and internal links (navigating links from one page to another on the same website). Frontend developers are responsible for ensuring correct display across different browsers and devices. They will encode the website in a way that makes it responsive or adapt to a variety of screen sizes so that the user can get the same information whether you visit the website on mobile, desktop, or tablet.

Frontend engineers will perform usability tests and fix any bugs that appear. At the same time, they will look for the best SEO techniques, maintain software flow management, and develop tools that improve the way a user interacts with a website in any browser.

Role of a backend Developer

The backend is actually the brain behind the face (frontend). The backend developer is therefore responsible for building and maintaining the technology needed to enable the frontend, which has three components: server, application and database.

The code developed by the backend manufacturers ensures that everything the frontend engineer builds is fully operational, and it is the backend engineer’s job to ensure that the server, application and database are all connected. Now how do they do it? First, they use server-side languages ​​like PHP, Ruby, Python and Java to build the application. They then use tools like MySQL, Oracle and SQL Server to retrieve, save or edit data and restore it to the user in the frontend code.

Like previous engineers, backend engineers will contact a client or business owner to understand their needs and requirements. They will present this in many ways depending on the details of the project. Typical back-end development tasks include creating, integrating and managing a database, building software-side software using backend frameworks, developing and deploying content management systems (blog, for example), and working with web server technology, API integration and operating systems.

Backend engineers are also responsible for checking and correcting errors in any program or application backgrounds.

Role of a full-stack developer

A full stack developer is someone who understands, and can work beyond, a “full stack” of technology: e.g. Front and back. Full stack developers are experts at all stages of the web development process, which means they are well-equipped to get their hands on it, but they can also guide strategies and best practices.

Most full-fledged stack developers have accumulated years of knowledge in a wide variety of applications, providing them with a solid foundation for the entire web development spectrum. Full-time developers are competent in both front and back languages ​​and frameworks, as well as in server, network and hosting environments. They also have good experience in both business minds and user experience.

Role of a Mobile developer

Web developers can work specifically on mobile app development, either for iOS or Android.

IOS developers are developing applications that run on the iOS app — used by Apple devices. IOS developers are familiar with Swift, a programming language developed by Apple specifically for their apps.

Android developers are building apps that are compatible with all Android devices, such as Samsung smartphones. Java is the official programming language for Android.

5. Know about programming languages, libraries, and frameworks.

To build websites and applications, web developers work with languages, libraries, and frameworks. Let’s take a look at each of these items in detail, as well as some of the tools web developers use in their day-to-day work.

What are the languages?
In the world of web development, languages ​​are the building blocks used by programs to create websites, applications and software. There are all kinds of languages, including programming languages, language languages, style sheet languages ​​and stored languages.

Planning languages
System language is actually a set of commands and commands that tell a computer to produce something. Programmers use so-called “high-level” languages ​​to write source code editors. Advanced languages ​​use logical terms and symbols, making it easier for people to read and understand. Advanced languages ​​can be classified as integrated or translated languages.

C ++ and Java, for example, are combined with high-quality languages; they are first stored in a text-based format that is understandable to human programming but not on computers. For a computer to use source code, it needs to be translated into a lower language; i.e. machine code. Combined languages ​​are often used to create software applications.

Translated languages ​​such as Perl and PHP do not need to be combined. Instead, the source code written in these languages ​​can be processed by an interpreter — a program that reads and applies the code. Translated languages ​​are often used to create texts, such as those used to create dynamic website content.

Low-level languages ​​are those that can be directly detected and created on computer hardware; they do not need to be translated or interpreted. Sign language and assembly language are some of the most common examples of low-level languages.

Some of the most popular editing languages ​​of 2018 include Java, C, C ++, Python, C #, JavaScript, PHP, Ruby and Perl.

Markup languages

Marking languages ​​are used to specify text file formatting. In other words, the markup language tells software that shows the text how the text should be formatted. Markup languages ​​are fully readable to the human eye — contain common words — but tag tags are not visible in the final output.

The two most popular dance languages ​​are HTML and XML. HTML stands for HyperText Markup Language and is used for website building. When added to a plain text document, HTML tags define how this document should be displayed by a web browser. To understand how HTML works, let’s take the example of bold tags. The HTML version will be written as follows:

Style sheets

Styles of style sheets have been used, literally, to create a style of text written in light languages. Consider HTML and style text using CSS (Cascading Style Sheets), the style sheet language. HTML covers the content and structure of a web page, while CSS determines how this content should be presented visually. CSS can be used to add colors, change fonts, add backgrounds and borders, and style forms. CSS is also used to enlarge web pages with responsive design, ensuring that they convert their format to any device the user is on.

Database languages

Languages ​​are not only used to build websites, software and applications; are used to create and manage information.

Data is used to store large amounts of data. The Spotify Music app, for example, uses information to store music files, as well as data about user listening preferences. Similarly, social networking apps such as Instagram use data to store user profile information; every time a user updates his or her profile in some way, the app’s database will also update.

Data is not designed to understand the same languages ​​that applications are installed in, so it is important to have a language that they understand — such as SQL, common language for accessing and managing information. SQL stands for Structured Query Language. It has its own builders, and basically enables system editors to work with data stored in the data system.

What are libraries and frameworks?

Web developers work with libraries and frameworks. Without much confusion, it’s not the same thing — though both are there to make the engineer’s job easier.

Libraries and frames are actually a set of pre-written code, but libraries are small and often used for specific use cases. The library contains a collection of useful code, which has been put together for later use. The purpose of the library is to enable developers to achieve the same end goal while compiling a small code to get there.

Let’s take the example of JavaScript, language, and jQuery, the JavaScript library. Instead of writing, say, ten lines of code in JavaScript, an engineer can take an abridged version, pre-written in the jQuery library — saving time and effort.

The framework contains ready-made materials and tools that enable the developer to write code quickly, and many frameworks also contain libraries. It gives the developer the structure to work on, and the framework you choose to work with will greatly determine how you build your website or app, so choosing a framework is a big decision. Other popular frameworks include Bootstrap, Rails, and Angular.

An easy way to understand libraries and structures is to imagine building a house. The framework provides the basis and structure, as well as instructions or guidelines for the completion of specific tasks. Say you want to install an oven in your new home: you can buy different items and build an oven from scratch, or you can choose a ready-made oven in the store. Like building a website, you can write code from scratch or you can take pre-written code from the library and just enter it.

6. How to become a web developer?

Web development work is challenging, financially rewarding, and there is plenty to offer in terms of job security. The Bureau of Labor Statistics predicts a 15% increase in web developer hiring between 2016 and 2026 — much faster than average — and the web engineer has been ranked as the eighth most innovative technical work in technology-based on salary and recruitment levels.

At the time of writing, the average salary of a web developer in the United States is $ 76,271 a year. Of course, salary varies according to location, years of experience, and the specific skills you bring to the table; find out more about how much you can earn as a web developer here.

The first step in web development work is to learn the necessary languages, libraries, and frameworks. You will also need to familiarize yourself with some of the tools mentioned above, as well as some common terms. For a friendly introduction, start with these 50 web development buzzwords that all new developers should learn.
