title: Comparison with the Less Than Operator
challengeType: 1
videoUrl: 'https://scrimba.com/c/cNVRWtB'
---
## Description
<section id='description'>
The <dfn>less than</dfn> operator (<code>&lt;</code>) compares the values of two numbers. If the number to the left is less than the number to the right, it returns <code>true</code>. Otherwise, it returns <code>false</code>. Like the equality operator, <dfn>less than</dfn> operator converts data types while comparing.
<strong>Examples</strong>
```js
2 < 5 // true
'3' < 7 // true
5 < 5 // false
3 < 2 // false
'8' < 4 // false
```
</section>
## Instructions
<section id='instructions'>
Add the <code>less than</code> operator to the indicated lines so that the return statements make sense.
</section>
## Tests
<section id='tests'>
```yml
tests:
- text: <code>testLessThan(0)</code> should return "Under 25"
testString: assert(testLessThan(0) === "Under 25");
- text: <code>testLessThan(24)</code> should return "Under 25"
testString: assert(testLessThan(24) === "Under 25");
- text: <code>testLessThan(25)</code> should return "Under 55"
testString: assert(testLessThan(25) === "Under 55");
- text: <code>testLessThan(54)</code> should return "Under 55"
testString: assert(testLessThan(54) === "Under 55");
- text: <code>testLessThan(55)</code> should return "55 or Over"
testString: assert(testLessThan(55) === "55 or Over");
- text: <code>testLessThan(99)</code> should return "55 or Over"
testString: assert(testLessThan(99) === "55 or Over");
- text: You should use the <code>&lt;</code> operator at least twice
testString: assert(code.match(/val\s*<\s*('|")*\d+('|")*/g).length > 1);
```

## Challenge Seed
<section id='challengeSeed'>
<div id='js-seed'>
```js
function testLessThan(val) {
if (val) { // Change this line
return "Under 25";
}
if (val) { // Change this line
return "Under 55";
}
return "55 or Over";
}
// Change this value to test
testLessThan(10);
```
</div>
</section>
## Solution
<section id='solution'>
```js
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";
}
```
