--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. The strict inequality operator will not convert data types.

Examples

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

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

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

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

testStrictNotEqual(12) should return the string Not Equal

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

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

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

You should use the !== operator

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

--seed--

--seed-contents--

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

testStrictNotEqual(10);

--solutions--

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