## Use the some Method to Check that Any Elements in an Array Meet a Criteria
### Problem Explanation
Use the some method inside the checkPositive function to check if any element in arr is positive. The `checkPositive` function should return a Boolean value.
#### Relevant Links:

### Solution:
```javascript
function checkPositive(arr) {
return arr.some((elem) => elem > 0);
}
checkPositive([1, 2, 3, -4, 5]);
```
