lodash.flatten

What is lodash.flatten?

The lodash.flatten package is a utility library that provides a method to flatten nested arrays into a single array. This can be particularly useful when dealing with multi-dimensional arrays and you need to simplify them into a single list of elements.

What are lodash.flatten's main functionalities?

Flattening a nested array

This feature allows you to take a nested array and flatten it by one level. The code sample demonstrates how to use lodash.flatten to convert a nested array into a single-level array.

const flatten = require('lodash.flatten');
const nestedArray = [1, [2, [3, [4]], 5]];
const flatArray = flatten(nestedArray);
console.log(flatArray); // Output: [1, 2, [3, [4]], 5]
