Array.prototype.every()
Array.prototype.every() checks if all elements in an array pass a given test.
"I want to make sure every item in my list meets certain criteria without writing a loop."
Array.prototype.every() executes a callback function on each element of an array and returns true only if all elements pass the test. If any element fails, it returns false immediately.
