These are added to add explanations to the existing code so that if a new person comes, he is able to understand what has happened in a snippet of code. These do not take any part in the functional behavior of the code.

Example

<script>
var a = 10; //value of a 
var b = 20; //value of b
var c = 5; //value of c 
/* This is a multi line 
comment */ 
var result = a + b * c; 
alert("Result is: " + result);
</script>
