How does lodash.zipWith work?
lodash.zipWith is a function provided by the Lodash library that merges corresponding elements from two or more arrays using a custom function to determine the value of each new element. It creates a new array of the same length as the input arrays, with each element being the result of calling the custom function on the corresponding elements of the input arrays.

In this example, lodash.zipWith takes two arrays ([1, 2] and [3, 4]) and a callback function (add) that is called with each pair of elements from the input arrays. The result is a new array ([4, 6]) where each element is the result of calling the add function with the corresponding elements from the input arrays.
