title: Use the every Method to Check that Every Element in an Array Meets a Criteria
challengeType: 1
---
## Description
The every method works with arrays to check if every element passes a particular test. It returns a Boolean value - true if all values meet the criteria, false if not.
For example, the following code would check if every element in the numbers array is less than 10:
var numbers = [1, 5, 8, 0, 10, 11];
numbers.every(function(currentValue) {
return currentValue < 10;
});
// Returns false
## Instructions
Use the every method inside the checkPositive function to check if every element in arr is positive. The function should return a Boolean value.
## Tests
```yml
tests:
- text: Your code should use the every method.
testString: assert(code.match(/\.every/g), 'Your code should use the every method.');
- text: checkPositive([1, 2, 3, -4, 5]) should return false.
testString: assert(!checkPositive([1, 2, 3, -4, 5]), 'checkPositive([1, 2, 3, -4, 5]) should return false.');
- text: checkPositive([1, 2, 3, 4, 5]) should return true.
testString: assert(checkPositive([1, 2, 3, 4, 5]), 'checkPositive([1, 2, 3, 4, 5]) should return true.');
- text: checkPositive([1, -2, 3, -4, 5]) should return false.
testString: assert(!checkPositive([1, -2, 3, -4, 5]), 'checkPositive([1, -2, 3, -4, 5]) should return false.');
```
## Challenge Seed
```js
function checkPositive(arr) {
// Add your code below this line
// Add your code above this line
}
checkPositive([1, 2, 3, -4, 5]);
