freeCodeCamp Challenge Guide: Comparison with the Equality Operator

Comparison with the equality operator


Problem Explanation

Add the equality operator to the indicated line so that the function will return “Equal” when val is equivalent to 12.


Hints

Hint 1

Remember that equality is different from assignment (=), which assigns the value at the right of the operator to a variable in the left.1


Solutions

Solution 1 (Click to Show/Hide)
function testEqual(val) {
  if (val == 12) {
    // Change this line
    return "Equal";
  }
  return "Not equal";
}
// Change this value to test
testEqual(10);

Code Explanation

The function first evaluates if the condition (val == 12) evaluates to true. 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”).
