Which algorithm does ES6 Array.find() use

Question

I have looked around but cannot find anywhere that states which algorithm Array.find() uses. Is it a simple loop or maybe a Binary search?

I guess it's different for each JS engine but there must be a consensus on how this function works.

Answer 1

Array.prototype.find() uses a simple linear search algorithm. It is not optimized for sorted arrays and does not use binary search or any other advanced search algorithm. It is designed to be general-purpose and works with any array and any testing function.
