56533eb9ac21ba0edf2244d6	Comparison with the Less Than Operator	1	https://scrimba.com/c/cNVRWtB	16789	comparison-with-the-less-than-operator

--description--

The less than operator (<) compares the values of two numbers. If the number to the left is less than the number to the right, it returns true. Otherwise, it returns false. Like the equality operator, the less than operator converts data types while comparing.

Examples

2   < 5
'3' < 7
5   < 5
3   < 2
'8' < 4

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

--instructions--

Add the less than operator to the indicated lines so that the return statements make sense.

--hints--

testLessThan(0) should return the string Under 25

assert(testLessThan(0) === 'Under 25');

testLessThan(24) should return the string Under 25

assert(testLessThan(24) === 'Under 25');

testLessThan(25) should return the string Under 55

assert(testLessThan(25) === 'Under 55');

testLessThan(54) should return the string Under 55

assert(testLessThan(54) === 'Under 55');

testLessThan(55) should return the string 55 or Over

assert(testLessThan(55) === '55 or Over');

testLessThan(99) should return the string 55 or Over

assert(testLessThan(99) === '55 or Over');

You should use the < operator at least twice

assert(code.match(/val\s*<\s*('|")*\d+('|")*/g).length > 1);

--seed--

--seed-contents--

function testLessThan(val) {
  if (val) {  // Change this line
    return "Under 25";
  }

  if (val) {  // Change this line
    return "Under 55";
  }

  return "55 or Over";
}

testLessThan(10);

--solutions--

function testLessThan(val) {
  if (val < 25) {  // Change this line
    return "Under 25";
  }

  if (val < 55) {  // Change this line
    return "Under 55";
  }

  return "55 or Over";
}
