Javascript shorthand for true or false in function

Is there a shorthand way of doing this so that the outcome is always true or false?

function trueFalse() {
  if( a == 1 ) {
    return true;
  } else {
    return false;
  }
}

Something like return true:false; and no need for the else section?

Thanks.

Just to make it even shorter and allow for any comparison...

const trueFalse = (a, b) => a === b;

(a few years after OP question but this would now also work)

ES6 shorthand would allow you to use a conditional operator:

const trueFalse = a === 1 ? true : false

Or even shorter but a bit less readable:

const trueFalse = a === 1

That would be:

function trueFalse(){
  return a === 1;
}

Also, as much as possible, use strict comparison.
