Omitting the second expression when using the if-e

Question

Can I write the 'if else' shorthand without the else?

var x=1;

x==2 ? dosomething() : doNothingButContinueCode();   

I've noticed putting null for the else works (but I have no idea why or if that's a good idea).

Edit: Some of you seem bemused why I'd bother trying this. Rest assured it's purely out of curiosity. I like messing around with JavaScript.

Another option:

x === 2 ? doSomething() : void 0;
