56533eb9ac21ba0edf2244d7 Comparison with the Less Than Or Equal To Operator 1 https://scrimba.com/c/cNVR7Am 16788 comparison-with-the-less-than-or-equal-to-operator

--description--

The less than or equal to operator (<=) compares the values of two numbers. If the number to the left is less than or equal to the number to the right, it returns true. If the number on the left is greater than the number on the right, it returns false. Like the equality operator, less than or equal to converts data types.

Examples

4   <= 5  // true
'7' <= 7  // true
5   <= 5  // true
3   <= 2  // false
'8' <= 4  // false

--instructions--

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

--hints--

testLessOrEqual(0) should return "Smaller Than or Equal to 12"

assert(testLessOrEqual(0) === 'Smaller Than or Equal to 12');

testLessOrEqual(11) should return "Smaller Than or Equal to 12"

assert(testLessOrEqual(11) === 'Smaller Than or Equal to 12');

testLessOrEqual(12) should return "Smaller Than or Equal to 12"

assert(testLessOrEqual(12) === 'Smaller Than or Equal to 12');

testLessOrEqual(23) should return "Smaller Than or Equal to 24"

assert(testLessOrEqual(23) === 'Smaller Than or Equal to 24');

testLessOrEqual(24) should return "Smaller Than or Equal to 24"

assert(testLessOrEqual(24) === 'Smaller Than or Equal to 24');

testLessOrEqual(25) should return "More Than 24"

assert(testLessOrEqual(25) === 'More Than 24');

testLessOrEqual(55) should return "More Than 24"

assert(testLessOrEqual(55) === 'More Than 24');

You should use the <= operator at least twice

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

--seed--

--seed-contents--

function testLessOrEqual(val) {
  if (val) {  // Change this line
    return "Smaller Than or Equal to 12";
  }

  if (val) {  // Change this line
    return "Smaller Than or Equal to 24";
  }

  return "More Than 24";
}

testLessOrEqual(10);

--solutions--

function testLessOrEqual(val) {
  if (val <= 12) {  // Change this line
    return "Smaller Than or Equal to 12";
  }

  if (val <= 24) {  // Change this line
    return "Smaller Than or Equal to 24";
  }

  return "More Than 24";
}
