title: Comparison with the Less Than Operator
localeTitle: Comparación con el operador menor que
challengeType: 1
---

## Description
<section id='description'> 
El operador <dfn>menor que</dfn> ( <code>&lt;</code> ) compara los valores de dos números. Si el número a la izquierda es menor que el número a la derecha, devuelve <code>true</code> . De lo contrario, devuelve <code>false</code> . Al igual que el operador de igualdad, <dfn>menos que el</dfn> operador convierte los tipos de datos al comparar. 
<strong>ejemplos</strong> 
<blockquote>2 &lt; 5  // true<br>'3' &lt; 7  // true<br>5 &lt; 5  // false<br>3 &lt; 2  // false<br>'8' &lt; 4  // false</blockquote> 
</section>

## Instructions
<section id='instructions'> 
Agregue el operador <code>less than</code> a las líneas indicadas para que las declaraciones de devolución tengan sentido. 
</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: <code>testLessThan(0)</code> debe devolver &quot;Under 25&quot;
    testString: 'assert(testLessThan(0) === "Under 25", "<code>testLessThan(0)</code> should return "Under 25"");'
  - text: <code>testLessThan(24)</code> debe devolver &quot;Under 25&quot;
    testString: 'assert(testLessThan(24) === "Under 25", "<code>testLessThan(24)</code> should return "Under 25"");'
  - text: <code>testLessThan(25)</code> debe devolver &quot;Under 55&quot;
    testString: 'assert(testLessThan(25) === "Under 55", "<code>testLessThan(25)</code> should return "Under 55"");'
  - text: <code>testLessThan(54)</code> debe devolver &quot;Under 55&quot;
    testString: 'assert(testLessThan(54) === "Under 55", "<code>testLessThan(54)</code> should return "Under 55"");'
  - text: <code>testLessThan(55)</code> debería devolver &quot;55 o más&quot;
    testString: 'assert(testLessThan(55) === "55 or Over", "<code>testLessThan(55)</code> should return "55 or Over"");'
  - text: <code>testLessThan(99)</code> debería devolver &quot;55 o más&quot;
    testString: 'assert(testLessThan(99) === "55 or Over", "<code>testLessThan(99)</code> should return "55 or Over"");'
  - text: Debes usar el operador <code>&lt;</code> al menos dos veces
    testString: 'assert(code.match(/val\s*<\s*("|")*\d+("|")*/g).length > 1, "You should use the <code>&lt;</code> operator at least twice");'

## 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";
}
```
