Comments in Javascript

There are two ways to write comments in our JavaScript code.
The first way is to use // your comments .
The above can be used to comment only one line of code. Everything that is between the two tags will be ignored by JavaScript.

The second way is to use /* your comments */.
We use this when we want to comment multiple lines. Again, everything between the two tags is ignored by JavaScript.
