How does lodash.default work?

lodash.default is a library that provides a collection of utility functions for working with arrays, objects, strings, and more in JavaScript. It is designed to make working with data in JavaScript easier and more efficient.

The library is divided into several modules, each containing a set of related functions. Some of the most commonly used modules are lodash/core, lodash/array, lodash/collection, lodash/chain, and lodash/util.

The lodash/core module contains the most basic utility functions, such as clone, isEqual, and isNil. The lodash/array module provides functions for working with arrays, such as chunk, difference, and flatten. The lodash/collection module provides functions for working with objects and collections, such as map, reduce, and filter. The lodash/chain module provides functions for chaining operations together, such as map, filter, and groupBy. The lodash/util module provides various utility functions, such as noop, now, and uniqueId.

One of the main benefits of lodash.default is that it provides a consistent API for working with data, regardless of the differences between JavaScript environments (e.g., browsers and Node.js). Additionally, it provides many common utility functions that are not included in the core JavaScript language.

import _ from "lodash.default";

const numbers = [1, 2, 3, 4, 5];
const sum = _.sum(numbers);

console.log(sum); // Output: 15

In this example, we first import the lodash.default package using the ES6 import syntax. We then create an array of numbers and pass it to the _.sum() function provided by lodash.default. The function calculates the sum of all the numbers in the array and returns the result. Finally, we log the sum to the console.
