When

a = 0

This:

var foo = function() {
  if (a != 0) return true
  return false
}

Or this:

var bar = function() {
  if (a != 0) return true
  else return false
}

Answer 1

It gets optimized at compile time anyway, so no runtime difference.

As usual, you can argue about style. My 50 cents: the first variant (no explicit else) is nicer because it’s less code doing exactly the same.

Of course, in this case, you would do

return a != 0;

… but I think the question is meant to be general.
