Comments

Sometimes you want to add a note along with your code to explain it to the person coming after you. That’s what comments are for.

Single line comments

Single line comments start with // and is in effect until the end of the current line.

5+5; // this is a comment. Anything after //  will not be executed 

// console.log(5); // this code is now commented out. This is a good way of
// disabling some code without deleting it 

Multi Line comments

Comments can span across lines if you start with /* and end with */. Anything between those markers is considered a comment.

/*
TODO: 
1. Clean this code up
2. Write better function
*/

/* alert() */

/* console.log();
alert() */
