Javascript IF statement with null condition error

Question

In the following IF statement, one of the conditions is sometimes null.

Parse.User.current() can be null, in which case I'll get this error:

Uncaught TypeError: Cannot read property 'id' of null

Is there an elegant way to avoid this error?

if( post.get("parent").id != Parse.User.current().id ) {

}

A cleaner way can be :

var current = Parse.User.current();

if(current && post.get("parent").id !== current.id ) {

}

Then check like this

if(Parse.User.current() !== null)
{
if( post.get("parent").id !== Parse.User.current().id ) {
//Do whatever necessary
}
}
