Lesson: Returning Boolean Values from Functions

You may recall from Comparison with the Equality Operator that all comparison operators return a boolean true or false value.

A common anti-pattern is to use an if/else statement to do a comparison and then return true/false:

function isEqual(a,b) {
  if(a === b) {
    return true;
  } else {
    return false;
  }
}

Since === returns true or false, we can simply return the result of the comparison:

function isEqual(a,b) {
  return a === b;
}
