how to learn javascript

People say that the best way to learn programming is to start with JavaScript (or JS for short). However, for beginners, learning JS may be a bit difficult. In this article, I will teach you how to learn JS, including learning steps, learning materials, and tools that can easily help you master JS.

Although the way to learn JS today is easier than before, it still takes a certain amount of time to master JS. The following are the steps to learn JS:

Step 1: Understand the global knowledge of JS

Before learning JS, you need to understand some basic knowledge of programming, such as constants, variables, data types, etc. Beginners need to understand the overall knowledge of JS first, because this is very important and is the basis for most other content about JS.

Step 2: Learn the syntax of JS

After understanding the global knowledge of JS, you need to start learning the syntax of JS. The syntax of JS is the core part of it. Please note that learning the syntax of JS takes some time. But if you go through the process, you'll be able to write some really cool stuff.

Step 3: Master the Web Technology of JS

JS is most commonly used to write dynamic web applications. Therefore, mastering the web technology of JS is one of the necessary steps to master JS. This includes mastering DOM manipulation and event handlers.

Step 4: Read the JS documentation

Once you have mastered the basic knowledge of JS and learned the syntax and web technologies of JS, you need to read the JS documentation. Reading JS documentation can help you understand more features and details of JS. This will give you a deeper understanding of the JS language, allowing you to write code with more confidence.

Step 5: Complete JS practice projects

Finally, completing some projects can help you become more familiar with JS. This will provide powerful practical opportunities and help you become familiar with JS to solve some larger-scale problems.

Now that we have the steps to learn JS, here are the learning tools and materials:
