How to Comment JavaScript Code

In this blog you will learn How to Comment JavaScript code.

Introduction

 

When we write JavaScript code we need to comment sometimes to state description or text or some explanation while writing the code, we need to comment on some lines in the code.

 

There are two types of comments,

1. Single line
2. Multi-line

For the Single-line comments, you can use “//”.

 

As for example

//This is a variable
var x = 0;
var x = 0; // This is a variable
For the Multi line comments, you
/*
Here you can comment multiple lines within them
*/
As
for example
/*
This is a variable
This is a variable
This is a variable
This is a variable
*/
var x = 0;
