Statement Terminator Using Semicolon

I just realised that in this particular video that the semicolon was not added to the end of the var. I tried the same with console and other commands and it seemed to work just fine. In Java for instance the code will give an error if the semicolon is missing (I realise they are completely different). Is omitting the semicolon a good practice? Does it later affect the code in anyway? Since it seems to be executing anyways.

Thanks

You're right that adding semicolons at the end of statements in Javascript is not required for the code to run properly. It is a good practice to add them however, since it makes the code clearer and more maintainable. Also if you minify Javascript code for production servers, omitting semicolons can cause syntax errors in some cases that were not there before minification.
