Comments in JavaScript

Two types of Comment

Single line comments start with //.
Text between // and the end of the line will be ignored by JavaScript.

// you can assign any type of value
var imvalue = 101;

var imvalue = 101; // assign any type of value

Multi-line comments start with /* and end with /.

Any text between / and */ will be ignored by JavaScript.

Ex: –
/* Comment Here */

Adding // in front of a code line changes the code lines from an executable line to a comment.

var imvalue = 101;
// var imvalue = 101;
