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;
}

Instructions

Fix the function isLess to remove the if/else statements.
