What does the `every()` method do in JavaScript?

The every() method in JavaScript is designed to test whether all elements in an array meet a certain condition specified by a function. When you invoke this method, it executes the provided function for each element in the array, effectively checking whether each individual element satisfies the specified criteria.

If all elements pass the test, every() returns true, indicating that the condition is universally met throughout the entire array. Conversely, if any single element fails to satisfy the test, it immediately returns false, signaling that the requirement is not universally applicable.

For example, if you have an array of numbers and want to check if all are greater than zero, utilizing every() would allow you to efficiently determine this in one pass through the array.

In contrast, the other responses don't accurately describe the functionality of every(). One option suggests it executes a function once for each array element, which aligns more closely with the forEach() method. Another response implies it tests if at least one element passes a condition, which describes the some() method. Lastly, there’s an option that states it returns a new array of elements passing a test; that behavior is characteristic of the filter() method.
