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.

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

Spoiler alert!

Solution ahead!

Basic code solution:

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").
