freeCodeCamp Challenge Guide: Practice comparing different values

Practice comparing different values


Hint 1

Remember from last exercises that unlike the equality operator, which attempts to convert both values being compared to a common type, the strict equality operator does not perform a type conversion.1


Solution 1 (Click to Show/Hide)
// Setup
function compareEquality(a, b) {
  if (a === b) {
    // Change this line
    return "Equal";
  return "Not Equal";

// Change this value to test
compareEquality(10, "10");

Code Explanation

The function first evaluates if the condition (a === b) evaluates to true considering both type and value. If it does, it returns the statement between the curly braces (“Equal”). If it doesn’t, it returns the next return statement outside them (“Not equal”).
