What you need to know before learning JavaScript

Beginners learning a language like JavaScript, especially on their own, often do errors in the code that prevent them from learning efficiently, quickly and above all correctly. Today’s article highlights common JavaScript language misconceptions and tips for beginner programmers.

JavaScript and Java

It’s often a myth among beginners that Java and JavaScript are closely related. It’s not true. In fact, they are similar except for the four letters of the name and the C-like syntax. How the JavaScript name was formed, Wikipedia knows very well.

The language was originally called LiveScript and was intended for both client-side programming and server-side programming (where it was to be called LiveWire). The syntax was influenced by C and Java, and since Java was a buzzword at the time, LiveScript was renamed to JavaScript on December 4, 1995, under license from Sun.

JavaScript is an object-oriented scripting language and is not used to develop stand-alone applications or applets. It is most commonly found in HTML documents and only runs in browsers. Java, on the other hand, is an object-oriented programming language and is used to create applications that run both in browsers and in virtual machines. Also, Java code needs to be compiled, whereas JavaScript is an interpreted language.

Learn HTML and CSS

For some, this may already seem logical and obvious, but it’s still worth paying attention to – before you start learning JavaScript, you should learn to understand the HTML markup language and the CSS styling language, because JS interacts closely with them.

Formatting Style

If you can get into the habit of sticking to one style of code formatting, your code will be easy to read and understand. This includes ways to organize braces, use of indents and spaces, etc. All this does not affect the operation of the code, but it will be easier for you to understand it later.

Understandable names

There are situations where the JS code consists of a large number of lines. In order not to forget what exactly a variable was declared for at the beginning of the code, it is better to give it a meaningful name.

Study of other works

Sometimes it happens that the developer finds himself in a dead end and does not know how to solve the problem further. Then he starts looking for clues and solutions from others. It’s not a call to borrow someone else’s code, you can just familiarize yourself with it and maybe even find a better way. Also, you will learn to understand code written by another person, because there are situations where you need to refine and correct someone else’s work.

Debugging tools and frameworks

If your script isn’t working properly, you don’t know what’s wrong, and you’re on the verge of a nervous breakdown, use some helpful tools for web developers.

Spend some time learning the frameworks – it will save you from writing boilerplate code and worrying about cross-browser compatibility. Many projects have been implemented using frameworks, and there may be times when you need to fix or finish something in them.

Find simple solutions

Reinventing the wheel can be rewarding, except when it comes to real, real projects. A smart approach is needed here. If you need to implement a task, first look for ready-made solutions. If you don’t and start solving the problem yourself, your code might be too long and complicated, and everything could fit in two simple lines.

Conclusion

When you start learning JavaScript, don’t be afraid of mistakes and don’t give up, because by going through a difficult learning path, you gain valuable experience and knowledge. We wish you creative success!
