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

--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
1 != "1"
1 != '1'
1 != true
0 != false

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

--instructions--

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

--hints--

testNotEqual(99) should return the string Equal

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

testNotEqual("99") should return the string Equal

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

testNotEqual(12) should return the string Not Equal

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

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

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

testNotEqual("bob") should return the string 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";
}
