--- title: Use the every Method to Check that Every Element in an Array Meets a Criteria --- ## Use the every Method to Check that Every Element in an Array Meets a Criteria ### Problem Explanation: Use the `every` method inside the `checkPositive` function to check if every element in `arr` is positive. The function should return a Boolean value. #### Relevant Links: - [Array.prototype.every()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/every) ### Hint Don't forget `return`. ## Solution ```javascript function checkPositive(arr) { // Add your code below this line return arr.every(val => val > 0); // Add your code above this line } checkPositive([1, 2, 3, -4, 5]); ``` ## Alternative Solution ```javascript function checkPositive(arr) { // Add your code below this line return arr.every(function(value) { return value > 0; }); // Add your code above this line } checkPositive([1, 2, 3, -4, 5]); ```
