How to learn JavaScript in 12 weeks

Today, learning JavaScript is an essential requirement for anyone who wants to dedicate himself to web development. Without a doubt, the developer profile is one of the most requested by companies. Furthermore, it is no longer a preserve reserved for great minds. Nor is it an exclusive area for computer scientists. Programming is becoming increasingly important and has been on the lips of everyone for a couple of years. In the digital sector, nobody wants to be left off the hook, and for this, it is necessary to learn JavaScript.

Why learn JavaScript?

The profile of the JavaScript programmer is highly valued. In fact, according to the latest survey, it is among the programming languages with the least stoppage. For this reason, more and more people are training to train in this area. If what you want is to take the leap and enter the job market in the digital sector, why not start with one of the most widely used and in demand languages? We are going to give you the keys to learn JavaScript in 12 weeks.

Keys to learning JavaScript

Make no mistake, learning a new programming language without having a rationale can be quite complex. A programmer's life does not consist of sitting in front of an application in which, by means of basic instructions, the content is generated. On the contrary, the programmer is the one who develops the application. For this, it is necessary to be able to abstract and think “from the other side”. In other words, put yourself at the feet of users to create a solid product that meets their needs.

Step One: The Logic of Programming

The first step is to focus on the fundamentals of programming. It is essential to understand why each line of code returns one or the other results.

Perhaps the beginning can be slow. Don't panic, the trick is to be persistent and not throw a towel. In the first weeks of the learning process, the key is to lay a good foundation. This is essential to understand and assimilate the more complex concepts that will come later.

Learning to program in JavaScript is similar to the learning process of any spoken language. When we study a language, the first thing we learn is the vocabulary to be able to use it in all the structures learned. In this way, we can begin to form sentences that allow us to communicate with other people who speak the same language. With JavaScript, the same thing happens. For this reason, the first 4 or 5 weeks is essential to internalize the basic concepts of the language such as conditionals, loops, creation, and assignment of variables, functions...

Thanks to this, we can start creating projects. All this learning must be based on constant practice. Learning a programming language like JavaScript theoretically is a waste of time. Never forget that programming is learned by programming!

From day one, we have to start "mincing" lines of code. Only then will we know what happens when we fail. It is vital to know how errors can be interpreted and what tools can fix them. If we do not program, it isn't easy to learn a language as extensive and with as many possibilities as JavaScript.

Eye! Patches will only bring trouble

In the world of programming, not everything goes as long as our web application works. Although they can help us achieve results, some practices will not help us understand programming logic. We are talking about the famous "patches". Copying and pasting a solution from the Internet is not programming, it is copying and pasting. This way of acting leads us to a very big basic problem. If the creation of a project is based on the union of many remnants, it will be very difficult to add functionalities later.

Second step: Frameworks

Once the fundamentals of the language are internalized, the next step is to set a bigger goal. The time has come to put ourselves to the test, to challenge ourselves. To achieve these advances, it is necessary to know other tools. What in the world of programming is known as “frameworks”. We can define framework as a tool that serves as a base structure and support to organize the code. The objective of this type of tool is to facilitate the work of programmers. In addition, it serves as a skeleton for the project and allows the automation of many processes.

Learning these new technologies allows us to make the leap to the most current web development. At the same time, it allows us to learn about such novel concepts as reactive programming, component development, or new DOM access techniques.

Learning a framework like the ones named above could take approximately 5 weeks. At this time, it is important to internalize the theoretical part and carry out different projects to be able to handle each of the tools that they offer us with ease and confidence.

Third step: Introduction to NodeJS

After spending the first few weeks learning JavaScript’s fundamental vocabulary and getting to know the frameworks, the next step would be to introduce NodeJS, the most important JavaScript execution engine today. With this last step, we would be able to place the JavaScript code that we already know how to develop in all areas of a web project.

What is the best formula to learn JavaScript?

The possibilities that JavaScript gives us as a programming language are endless. Starting from web development (its natural habitat), through the development of mobile applications or even the creation of chatbots with recognition of natural language. For these reasons, the profile of the JavaScript programmer is one of the most demanded by companies and one of the best paid jobs. As we have explained throughout this article, it is possible to learn JavaScript in 12 weeks. But beware! You must know that if you want to learn JavaScript on your own, the learning period will be much longer.
