moment VS lodash

We could control the DST flip by setting the test's input time to the appropriate time of year (summer/winter). However we couldn't control the timezone. We had to adjust the expected data in the test 🤢 using the same library which the production code used (momentjs).

8. Moment.js

This may sound a bit general but we can't forget about well-tought code. If we are using a lot of external dependencies, we can check if there aren't many lighter alternatives. Example? Some people are still using moment.js for date formatting. Why not use a lightweight 2kb alternative instead? Writing clean, organized and maintainable code won't give us a huge score boost but we are trying to save every byte of data, right? 😉

We all know the pain of working with dates in Javascript. It needs to be more explicit, has almost no method, and could not be more clunky. For example, to create the Date January 1, 2023, you have to write a new Date (2023, 0, 1), which can be confusing for beginners, and overall just not that clear. And because of these reasons, the community has made many libraries that attempt to make Date easier to work with over the past years. Like momentjs or Date-fns. But the good news is that you won't need these third-party libraries any longer. The Temporal Date API in Javascript attempts to completely replace the Date object and fix all of the issues we generally face when working with dates.

moment was put into maintenance mode in 2020 and has gained 7 million weekly downloads to 19 million/week since then.

Moment is a JavaScript date library for parsing, validating, manipulating, and formatting dates. It allows displaying of date as per localization and in a human-readable format.

Luxon is a powerful and lightweight JavaScript library for working with dates and times. It was created as an alternative to the popular Moment.js library, with the goal of being faster, smaller, and easier to use.

It allows users to create tasks, change their schedule and duration with drag-and-drop, add dependency lines, and review extra information on tasks via tooltips. You can add multiple timescales to the chart. The list of possible options includes Quarter Day, Half Day, Full Day, Week, and Month. There are also some customization opportunities such as changing the tooltip content with custom HTML, modifying the appearance of task bars and dependency lines, and setting the default timescale. It should be noted that Frappe Gantt has two dependencies: momentjs and snapsvg.

https://momentjs.com/ is a useful library for this exact thing.

To help you quickly set up a project test with the Snyk CLI, a sample JavaScript project has been made available in this GitHub repository with all the necessary manifest files. The project is a simple quote API that uses Lodash and Express as their dependencies. The quote API has a GET / endpoint that returns a list of quotes and a GET /random endpoint that returns a random quote.

I don't think isEmpty is O(n) except in the case where the object is a prototype[1] - I assume that's one of those weird JS edge cases - otherwise it does what you expect, which is to iterate with a for-in loop and return on the first iteration, so it is O(1).

lodash/fp is an optional distribution of lodash that did what the core library did, but did so in a more flexible, powerful, composeable way that makes it easier to construct powerful functions. it was separate from the core, but based heavily on it. https://github.com/lodash/lodash/wiki/FP-Guide

at the time, nothing was settled. we were in a pioneering mode of building; we didn't know what people would find useful or what the future would hold. there were a lot of different ideas floating around, and lodash was trying to stay the same while also offer a port to this barely-subtly-different paradigm, to see what value might be found there. saying that "introduced" it feels like a crude reduction to me; he allowed people the option they asked for.

i personally think fp - in particular - "pointsfree" fp - has huge down sides to being understandable. but it also is a much more succinct and capable way of expressing things, and multiple times a week i run into situations where auto-currying or reverse args would make the code i write much cleaner & not damage code comprehension.

rather than call fp a fad, & insult the author for ever letting it in, i think there's room to say that it's sad that js had to stay on the lowest common denominator. the future was unable to be changed, the old ways stuck. we lost some really good opportunity & capabilities. that said, i still think the pointsfree style is hugely damaging & responsible for greatly reducing the chances we had to improve. instead, we're not "moving on", we're going back to square 1, to the only thing we've ever known or done. that makes me a little sad, to have the pioneering pack up & move back into the city.

The bigger news is that Lodash is migrating from Node.js to Bun: https://github.com/lodash/lodash/commit/97d4a2fe193a66f5f96d...

Frankly I commend the author. If you’re maintaining one of the most used open source packages, I think it must be overwhelming to get so much feedback. Realistically a team of 4 people probably working full time could manage a package like that and it seems like it’s just one guys side project.

They tagged 363 issues with "issue bankruptcy" and closed them: https://github.com/lodash/lodash/issues?q=is%3Aissue+is%3Acl...

Same for 325 PRs: https://github.com/lodash/lodash/pulls?q=is%3Apr+is%3Aclosed...

Hey! Thanks for sharing. I just want to point out that there are some tried and tested libraries out there that solve some of these problems already. You should check out `lodash`(https://lodash.com/) if you haven't already. Also, there is an array method called `splice` that could improve your implementation of `insert` at first glance.

Alright, now that I’ve got your interest piqued, let’s delve into the real stuff – tangible examples of Pythagora in action. For the purpose of our demonstration, we selected a well-known open source project, Lodash.

lodash : Data manipulation

lodash (56k ⭐) — This library provides a wide range of utility functions for JavaScript, including a kebabCase function that can be used to convert a string to kebab case, which is similar to slug format. Kebab case format is a naming convention where words are separated by a hyphen (-) and all letters are in lower case.
