lodash VS You-Dont-Need-Lodash-Underscore

Lodash.js is like the Swiss Army knife for JavaScript developers. Need to manipulate data structures or dabble in functional programming? Lodash is here to save the day with its arsenal of utilities. It's all about making your code cleaner and your life easier, which is probably why big guns like Google and Airbnb have it in their toolkit.

lodash - utility library enabling things like deep object comparison that aren't easy to do with javascript out of the box. docs

Lodash is a widely used JavaScript utility library that provides a plethora of functions to simplify common programming tasks. From manipulating arrays and objects to handling edge cases and implementing functional programming paradigms, Lodash offers a comprehensive toolkit for JavaScript developers. In this beginner's guide, we'll learn how to get started with Lodash and leverage its functionality to write cleaner, more efficient, and more maintainable code.

5. Lodash

If you want even more sophisticated equality checks like deep comparisons, there's the: lodash.iseQual library that'll do this for you out of the box. At least now you do have a bit of clarity on what's happening under the hood, so there's no harm in using a library.

It's also important to ensure that you're importing libraries correctly, so webpack can perform tree shaking effectively. For example, let's import lodash, as follows:

Lodash is awesome! It’s a JavaScript library that helps you do many things with data. You can use Lodash to manipulate arrays, objects, JavaScript strings, numbers, and more. It’s easy to get Lodash in your project. You can use npm or a CDN to install and import it. Here’s how:

Think of RxJS as Lodash for events.

lodash and You Might Not Need Lodash

A lot of Lodash functions are implemented as combinations of other Lodash functions, so importing a single function actually imports half of Lodash under the hood:

These are all really outdated tips. Moment is deprecated and it is recommended to use dayJs or date-fns. Lodash is discouraged because it has a huge bundle size and nowadays you will find native functions which do most of the things people have used lodash before. https://github.com/you-dont-need/You-Dont-Need-Lodash-Underscore

I never used lodash but I found this. Might interest you.

In one of my team's Pull Requests I noticed date-fns being added as dependency for our components library for one usage: transform a timestamp to "MM/yy" string, as it represented a debit card's expiration date. Inspired by You don't (may not) need lodash/underscore, I thought to myself - can't we just implement a 2-digit month and 2-digit year formatting? It looks simple, right?

Yes and no. We did but are converting to in-house code since most Lodash functions are already available as native JS and/or @babel/preset-env + core-js@latest (see: You don't need Lodash).
