## Description
|
||
|
<section id='description'>
|
||
|
The <code>less than or equal to</code> operator (<code><=</code>) 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 <code>true</code>. If the number on the left is greater than the number on the right, it returns <code>false</code>. Like the equality operator, <code>less than or equal to</code> converts data types.
|
||
|
<strong>Examples</strong>
|
||
|
<blockquote>4 <= 5 // true<br>'7' <= 7 // true<br>5 <= 5 // true<br>3 <= 2 // false<br>'8' <= 4 // false</blockquote>

## Instructions
|
||
|
<section id='instructions'>
|
||
|
Add the <code>less than or equal to</code> operator to the indicated lines so that the return statements make sense.

- text: You should use the <code><=</code> operator at least twice
|
||

testString: 'assert(code.match(/val\s*<=\s*(''|")*\d+(''|")*/g).length > 1, ''You should use the <code><=</code> operator at least twice'');'
