Consider the following code:

function danceLikeNoOnesWatching( person ) {
  if ( person.danceMoves === “amazing” ) {
    return false;
  } else {
    return true;
  }
}

Looks good right? It’s logical and easy to understand, just your standard if statement. All true, but over the course of an entire project you’ll make a lot of considtional statements like this and using 5 lines of code when 1 will do can create some serious size increases to your code. To reduce the codes size, just return the output of the conditional like this:

function danceLikeNoOnesWatching( person ) {
  return person.danceMoves === “amazing”;
}

Simpler, still easy to understand and now light weight.
