Testing all elements: `every()`

Testing all elements: every()

If you have an array and you want to check if all the elements satisfy a certain condition, you can use every() method on Array. For example, if you want to check that all the array elements are greater than 25, you can use this example:

// the array
const array = [32, 30, 39, 29, 100, 43]
(currentValue) => currentValue > 25
