How Can JavaScript Efficiently Generate All Combinations from Multiple Arrays of Varying Sizes?

Generating Combinations from n Arrays with m Elements in JavaScript

When dealing with arrays containing varying numbers of elements, it can be challenging to generate combinations from multiple arrays. Here, we delve into a JavaScript solution that effectively handles such scenarios.

The approach utilizes a recursive helper function to traverse the arrays and produce all possible combinations. The helper function begins by cloning the current array, adding an element from the current array, and either pushing the result into the final list or recursively continuing the traversal.

By modifying the function signature to accept an array of arrays, it can be effortlessly adapted to process complex array structures where each array may have different elements. This recursive method offers a concise and efficient way to generate all combinations from a collection of arrays, regardless of their size or structure.
