56533eb9ac21ba0edf2244d2	Comparison with the Inequality Operator	1	https://scrimba.com/c/cdBm9Sr	16787

--description--

The inequality operator (!=) is the opposite of the equality operator. It means "Not Equal" and returns false where equality would return true and vice versa. Like the equality operator, the inequality operator will convert data types of values while comparing.

Examples

1 !=  2     // true
1 != "1"    // false
1 != '1'    // false
1 != true   // false
0 != false  // false

--instructions--

Add the inequality operator != in the if statement so that the function will return "Not Equal" when val is not equivalent to 99

--hints--

testNotEqual(99) should return "Equal"

assert(testNotEqual(99) === 'Equal');

testNotEqual("99") should return "Equal"

assert(testNotEqual('99') === 'Equal');

testNotEqual(12) should return "Not Equal"

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

testNotEqual("12") should return "Not Equal"

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

testNotEqual("bob") should return "Not Equal"

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

You should use the != operator

assert(code.match(/(?!!==)!=/));

--seed--

--seed-contents--

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

testNotEqual(10);

--solutions--

function testNotEqual(val) {
  if (val != 99) {
    return "Not Equal";
  }
  return "Equal";
}
