--description--

In the last two challenges, we learned about the equality operator (==) and the strict equality operator (===). Let's do a quick review and practice using these operators some more.

If the values being compared are not of the same type, the equality operator will perform a type conversion, and then evaluate the values. However, the strict equality operator will compare both the data type and value as-is, without converting one type to the other.

Examples

3 == '3'  // returns true because JavaScript performs type conversion from string to number
3 === '3' // returns false because the types are different and type conversion is not performed

Note
In JavaScript, you can determine the type of a variable or a value with the typeof operator, as follows:

typeof 3   // returns 'number'
typeof '3' // returns 'string'

--instructions--

The compareEquality function in the editor compares two values using the equality operator. Modify the function so that it returns "Equal" only when the values are strictly equal.

--hints--

compareEquality(10, "10") should return "Not Equal"

assert(compareEquality(10, '10') === 'Not Equal');

compareEquality("20", 20) should return "Not Equal"

assert(compareEquality('20', 20) === 'Not Equal');

You should use the === operator

assert(code.match(/===/g));

--seed--

--seed-contents--

// Setup
function compareEquality(a, b) {
  if (a == b) { // Change this line
    return "Equal";
  }
  return "Not Equal";
}

compareEquality(10, "10");

--solutions--

function compareEquality(a,b) {
  if (a === b) {
    return "Equal";
  }
  return "Not Equal";
}
