Javascript is very lenient in its browser interpretation and most statements will have an assumed semi-colon, using Javascript's automatic semi-colon insertion (read more here: http://lucumr.pocoo.org/2011/2/6/automatic-semicolon-insertion/ ).
Best practice is to use the semi-colons.

Okay. I was just curious, i previously programmed in C++ and when i forgot to put a semi-colon to the code, program compilation was stopped. Thanks for the fast reply @mkmk :)

When you start working with Grunt for example you will be reminded to put a semicolon:)
