56533eb9ac21ba0edf2244d3 Comparison with the Strict Inequality Operator 1 https://scrimba.com/c/cKekkUy 16791 comparison-with-the-strict-inequality-operator

--description--

The strict inequality operator (!==) is the logical opposite of the strict equality operator. It means "Strictly Not Equal" and returns false where strict equality would return true and vice versa. Strict inequality will not convert data types.

Examples

3 !==  3
3 !== '3'
4 !==  3

In order, these expressions would evaluate to false, true, and true.

--instructions--

Add the strict inequality operator to the if statement so the function will return the string Not Equal when val is not strictly equal to 17

--hints--

testStrictNotEqual(17) should return the string Equal

assert(testStrictNotEqual(17) === 'Equal');

testStrictNotEqual("17") should return the string Not Equal

assert(testStrictNotEqual('17') === 'Not Equal');

testStrictNotEqual(12) should return the string Not Equal

assert(testStrictNotEqual(12) === 'Not Equal');

testStrictNotEqual("bob") should return the string Not Equal

assert(testStrictNotEqual('bob') === 'Not Equal');

You should use the !== operator

assert(code.match(/(val\s*!==\s*\d+)|(\d+\s*!==\s*val)/g).length > 0);

--seed--

--seed-contents--

// Setup
function testStrictNotEqual(val) {
  if (val) { // Change this line
    return "Not Equal";
  }
  return "Equal";
}

testStrictNotEqual(10);

--solutions--

function testStrictNotEqual(val) {
  if (val !== 17) {
    return "Not Equal";
  }
  return "Equal";
}
