Lodash _.chunk

Overview

The lodash _.chunk method is a utility function commonly used in JavaScript programming to split an array into smaller arrays of a specified size. This method takes in two arguments, the first being the array to chunk and the second being the size of each chunk.

The method returns an array of chunked arrays, with each chunk having a maximum size of the number provided in the second argument. If the last chunk is smaller than the specified chunk size, then it will also be included in the returned array.

An important feature of the _.chunk method is that it does not modify the original array. Instead, it creates a new array containing the chunked arrays. This makes it a safe method to use in situations where the original array needs to remain unchanged.

Here's an example of how to use the lodash _.chunk method:

const arr = [1, 2, 3, 4, 5, 6, 7, 8, 9];
const chunkedArr = _.chunk(arr, 3);
console.log(chunkedArr); // Output: [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

In the example above, the original array arr is split into smaller arrays of size 3 using the _.chunk method. The resulting array chunkedArr contains three arrays, each with a length of 3 (except for the last array which contains the remaining elements).

Overall, the lodash _.chunk method is a useful utility function for splitting arrays into smaller, more manageable chunks. Its ease of use and ability to return a new array make it a popular choice for a wide range of JavaScript programming applications.
