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.

Sometimes people use an if/else statement to do a comparison, like this:

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

But there's a better way to do this. Since === returns true or false, we can return the result of the comparison:

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

Another example:

 function isLess(a, b) { 
// Only change code below this line
 return a <= b;
 // Only change code above this line
}
isLess(10, 15);
