How do I learn JavaScript from home

Learn JavaScript and become a web developer

Learning JavaScript and web developers becoming ... even easier with frameworks

In an increasingly digital world, it is only natural that more developers will also be needed. Web developers in particular are often in demand, as they have to program a wide variety of websites and services for companies. But which programming language should you learn first? Clearly: JavaScript! We explain why.

Why JavaScript?

JavaScript is a programming language that makes websites more interactive. HTML is used to structure and define the content. CSS tells the browser how this HTML content should be presented. For example, colors and the font are specified. Strictly speaking, they are not programming languages ​​either, but markup languages ​​- a big difference. With HTML and CSS, you have a website that looks good, but doesn't do a lot. It is only through JavaScript that functions are added and “breathed” into life. The user can interact with the website, e.g. B. through drop-down menus or contact forms. Of course, JavaScript can do a lot more: It is also used to create animations, games, interactive maps or video players.

Good news: There is currently a huge shortage of skilled JavaScript developers. According to a 2020 study by, 70 percent of businesses are looking for JavaScript developers. The latest HackerRank 2020 report reports that JavaScript is the most popular language recruiters look for in a web developer candidate.

For example, if you enter the search term “JavaScript” on the Indeed job exchange, you will find over 16,000 jobs in Germany. The same search on the LinkedIn career platform leads to over 65,000 search results.

In addition, the average annual salary in the US is already between $ 73,000 and $ 102,000, but it is also rising steadily in this country. has average JavaScript developer salaries between € 57,000 and € 78,000. Many companies are so urgently looking for web developers that they can offer you lots of goodies such as a company car, home office or more vacation days.

In a nutshell: If you are looking for a job with a future that offers many opportunities for advancement, is versatile and also pays well - then you can hardly avoid JavaScript.

What is JavaScript needed for?

As a web developer or web developer, you mainly develop applications for the Internet. JavaScript is the first and only choice. This ranges from a simple website to complex forms or interactive applications.

Over the years, JavaScript has developed into a universally applicable programming language. You can now find JavaScript not only in the browser on your home computer, but distributed across the entire software stack.

Creating web pages with JavaScript naturally still plays an important role in the use of the programming language. But it can also be used to create browser-based games and mobile apps for different operating systems, for example.

What are the advantages of JavaScript?

  • JavaScript is the most popular programming language and is widely used.
  • As the standard language of the Internet to be found in every browser. Since browsers are almost indispensable in our daily lives, it is easy to see why JavaScript is so important.
  • JavaScript is also used as a language in SmartTVs and many other technologies.
  • The programming language is easy to learn.
  • JavaScript can be used in a variety of ways in the front and back end.
  • Desktop, mobile and web apps can also be created.
  • Even machine learning for artificial intelligence (AI) can be implemented with JavaScript.
  • Did anyone say game development here? The versatility of the language, its performance make it an alternative solution for game developers.
  • JavaScript experts are in great demand on the job market!

Important: Do not confuse the Java programming language with JavaScript. Java is an OOP (object-oriented programming language) programming language and JavaScript is a scripting language. Java must be compiled, whereas JavaScript can be executed directly. You can find a more detailed comparison here, for example.

Is it still worth learning JavaScript in 2021?

You hear about new programming languages, new tools and frameworks all the time - that can be confusing. Sure, as a budding developer you want to be sure that what you are learning will still be relevant tomorrow. Do you have any doubts? Then you should remember that JavaScript has lost none of its popularity since 1995. It can be found all over the web. According to a StackOverflow developer survey 2020, JavaScript is 67.7% eighth year subsequently the most frequently used programming language.

Which programming languages ​​should one also be able to master?

This is of course very difficult to answer in general, as the exact technology stack depends very much on the orientation. The focus in app development differs from that in the creation of websites.

HTML and CSS are not classic programming languages. However, mastering these is highly recommended. As a web developer, you should also be familiar with Git and software versioning. It is also an advantage to familiarize yourself with other methods and tools. The roadmap from provides a good overview. Don't feel overwhelmed, of course you don't have to learn everything at the beginning. It should serve much more as a guide.

What are frameworks?

A framework is something like a basic program, an application architecture. Instead of developing everything from scratch, you can use existing modules and components, which saves a lot of time and nerves. The most popular frameworks on the web include Angular, React and Vue.js. These frameworks are built on JavaScript.

Frameworks can also contain libraries. These libraries are usually smaller than frameworks and are used for special applications. A JavaScript library contains auxiliary functions that solve recurring problems and can be used regardless of the selected application architecture or framework. For example, if you want to transform a date like February 5th, 2021 into the American spelling 02-05-2021, you can do this yourself using a few (many) lines of JavaScript, or you can use a specialized date library. The best known JavaScript libraries are Lodash and jQuery.

As an analogy that does not come from the IT sector, one can, for example, orientate oneself to house building. You can find more examples here.

You could build a house without tools, but to make the work easier and to move more safely and quickly, you would certainly use tools. These can be used anywhere and in any way you need and want. This part depicts the libraries.

The foundation dictates how the house will be structured. You have to adhere to certain regulations, otherwise the house cannot be built properly. This framework represents frameworks in software development.

The big advantage of frameworks is the easier and faster development of applications.

Can you start right away with frameworks or do you have to learn JavaScript first?

Since frameworks are only an application architecture, you of course first need JavaScript knowledge to develop applications. The more experience you have with JavaScript, the better it is.

If you really want to work as a web developer, you will inevitably come across JavaScript everywhere. Learning the basic principles and the structure of the language makes you a versatile developer and employee who can work both in the frontend and in the backend. You can even make framework decisions with it and solve complex problems independently - a key qualification in this industry.

Which framework is suitable if you have mastered JavaScript?

Of course, this question is difficult to answer because it depends on the desired goals and skills. The Angular developed by Google stands for simple testability, structure and quality at enterprise level. React, published by Facebook, is quick to get started and a quick user interface. Vue.js, on the other hand, is completely independent, easy to learn and has a large and active community - an important factor when questions arise or support is needed. With more than 1.3 million users worldwide, Vue.js is currently one of the most successful JavaScript frameworks and is extremely popular. Vue.js is actually the middle ground between Angular (for enterprise applications) and React (for individual projects).

What are the advantages of the Vue.js Framework?

Vue is a client-side JavaScript web framework that can be used to create single-page web applications as well as more complex multi-page websites. The advantages include: improved performance (since version 3.0), 50% less rendering time compared to other frameworks, optimized runtime, the Composition API for improved code clarity, the innovative TypeScript core and, above all, the small size of only still 10 kB. It does not matter whether you want to build simple applications or complex interfaces with Vue.js - it is equally suitable. If you are looking for a simple, powerful and at the same time independent framework, you will find happiness with Vue.js.

And what is the next step now?
