How does lodash.stubArray work?

lodash.stubArray is a utility function provided by the Lodash library that creates a new array with a specific length, and fills it with undefined values. The function takes no arguments, and returns an empty array, which is useful for creating an array of a specific length when you don't need to fill it with specific values.

const _ = require("lodash");

const arr = [1, 2, 3];

const stubbed = _.times(3, _.stubArray);

// Stubbed is now: [[], [], []]

In this example, we require the lodash library and create an array arr with some numbers. We then use the _.times function to create an array stubbed with 3 elements, where each element is a new empty array created using the _.stubArray function. The resulting value of stubbed will be [[ ], [ ], [ ]]. The _.stubArray function creates a new empty array object and returns it, so that it can be used as a placeholder or default value.
