I've heard from lots of folks who want to enroll in my new React course, but can't afford it. I want to be able to share some high-quality free alternatives. I can think of a couple things (beta React docs, Odin Project), but I'm sure there are many wonderful options out there!

Also, yes, I am aware that I bounce while I talk. Lots of people have told me. 😅 That's just what happens when I'm enthusiastic. And I think “enthusiastic and bouncy” is better than “monotone and still”.

In “The Joy of React”, there's one video that a *bunch* of early testers told me they found really helpful. It's not technical at all. Instead, it focuses on “best practices”, and the stress that they can cause. It's short (≈4min)! Check it out: courses.joshwcomeau.com/videos/youre-d

Woah, totally forgot I did this 😅 I profiled a bunch of different layout algorithms in CSS, on a high-end machine and a low-end smartphone. The takeaway: there are some small differences, but they're all really friggin’ quick! ⚡️

Today I looked into the performance of different layout modes in CSS. I was curious if it takes the browser longer to lay out elements in a grid vs. Flexbox vs. flow layout. TL:DR; they're all plenty fast ⚡️ but there are small differences. Info in thread 👇🏻

Fun detail I hope people notice: the little fella has an arrow hand 😄 He was originally going to be pointing, but I quickly realized I have no idea how to draw a pointing hand.

I'm *super* excited about a newsletter issue I'm sending tomorrow. It's about “best practices”, and honestly, I think it's something most of us need to hear. 😄 Sign up here: joshwcomeau.com/subscribe/
Panel 1 of a two-panel comic. A cheeky stick figure is standing in front of some React code, presenting it to a group, saying "Hey folks! Check out this cool snippet I wrote!"
Panel 2 of a two-panel comic. The cheeky fellow looks crestfallen as they're subjected to criticism:

- You should include all of the dependencies in an array...
- This doesn't align with best practices
- Does this really need to be a hook?
- ...don't like... you did it... wrong... bad

I'm a little bit late to this, but the way Josh teaches things is unparalleled right now. If you're uncertain with React, or you want to understand it in more depth, you'd be doing yourself a disservice not picking up this course. It's excellent 🔥

I sprinted through the first section yesterday, and as a "react expert" I still learned a few new tricks. Something special about the courses creates is that I can jump in at any level of comfort with the technology and have something to learn.

As a student of 's CSS course, I cannot stress how much I enjoy Josh's way of teaching, would totally recommend his new React course. It's presently at early access for about a week, which only costs about half the total price. Seize the opportunity! #React

If you are learning React, or want to learn, ask your company if they'd buy you this course! A lot of companies have visible/hidden budgets for these kind of things, and content is top-notch! #react #reactjs

After a year of work, The Joy of React will be released in “Early Access” TOMORROW. 😄 When the course is released in full, the price will likely be US$399 or US$449, something like that. But tomorrow, you'll be able to nab it for ✨ $199 ✨. joyofreact.com

Just picked up 's new course! The CSS one was an incredible value and though I'm a bit more familiar with React (just enough to be dangerous), excited to learn through Josh's lens and deep dive vibes!

I can't think of many paid courses that I would wholeheartedly recommend to anyone, but Josh has proved time and time again that his material is just that good. If this course existed when I started learning React for the first time, I would have purchased it in a heartbeat 👏🏾

I haven't done the course, so I can't speak directly to it, but if I was going to dive into a React course today, I'd go with this one without hesitation. Josh is a great communicator and teacher I have no doubt that it's an amazing course.

If you've been struggling to understand React, I recommend checking out Josh's course! His content is ALWAYS top-notch. You won't just learn how to build "things", you'll build a true mental model of how they work under the hood.
