56533eb9ac21ba0edf2244d3	Comparison with the Strict Inequality Operator	1	https://scrimba.com/c/cKekkUy	16791

--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   // false
3 !== '3'  // true
4 !==  3   // true

--instructions--

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

--hints--

testStrictNotEqual(17) should return "Equal"

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

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

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

testStrictNotEqual(12) should return "Not Equal"

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

testStrictNotEqual("bob") should return "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";
}
