JavaScript beautifiers: The best 5 tools available

Javascript Beautifiers are a set of tools that we can use to format our Javascript code. The beautifiers can format code written in any programming language. In this article, our focus is on javascript. In this article, we will show the best beautifiers available for Javascript.

A little explanation about code formatting

Formatting your code manually is the work of the past now. There are plenty of code formatting websites, libraries and web scripts available to do the formatting part. In this article, we will learn about a few best ways of formatting code in javascript. But first we need to know what is the meaning of code formatting and why do we need it.
There is a proper format for writing a program. Although it is not necessary to write code in a specific format, the code always looks better when it is in a proper format. Observe the following code.
var x=4; var y=2; function add(a,b){
return a+b;}
var result;result = add(x,y);

The above code has two variables, one function and another variable where the function is called. But when we look at the code, it is very hard to understand. Debugging an unorganized source code is always a tough task. The code is not in a proper format. Even if the code is understandable to the person who wrote it, it will be difficult for others. If there is another person who had to work further on the above code, he will face difficulties. This is why code formatting is important. The following code is the formatted version of the above code.

var x = 4;
var y = 2;
function add(a, b) {
  return a + b;
}
var result;
result = add(x, y);
Compare both codes. We have not changed logic or variable names, the output is the same. But we formatted the code in a more readable format. This is called code formatting. But in the modern world, we do not need to format manually, instead, we can use various tools for it. These tools are known as beautifiers and we will discuss some best javascript beautifiers in this article.
