Bytes： Tailwind hits the big 4.0

Cool Bits

1. React Native 0.77 comes with multiple new CSS features for better layouts, sizing and blending. Because I guess everyone suddenly decided that CSS support is cool all of a sudden??

2. The Biome team shared their plans for Biome 2.0 and the rest of 2025.

3. Thomas Hu and Chetan Patil are hosting a livestream on How to build testing culture on your team. They’ll outline a step-by-step plan to help you steadily improve test coverage at your org – without micromanagement. [sponsored]

4. Kelly Sutton wrote an article called Moving on from React, a year later. How come the title of every blog post about migrating off React sounds like the title of a Love is Blind episode?

5. The Bad at CSS podcast just came out with a new episode called, What do backend devs think of CSS? You can probably already guess the answer to that question, but it’s a really good interview.

6. The Apryse OCR SDK provides enterprise-ready document conversion that lets you deliver exceptional accuracy, multilingual support, and seamless integration for your document workflows. [sponsored]

7. The Callstack team just released Flows AI, a lightweight library to build agent workflows on top of Vercel AI SDK.

8. Una Kravets wrote about the new capabilities for attr() that are coming to Chrome 133 next week. Personally, I’m offended that Tailwind doesn’t support this yet.

9. Superglue just released v1.0 of its library that lets you “use classic Rails to build rich React Redux applications with no APIs and no client-side routing.”

10. James Hawkins from PostHog wrote about How to not be a boring startup – because it turns out everyone judges books by their covers. Which is why my closed-minded drama teacher always cast me as “Ensemble Tree #3” in middle school. [sponsored]

11. Robert Fidler wrote about client state management, sync engines, and Foundry.

12. TikTok just released a Cursor IDE competitor called Trae. Apparently, Trump is forcing them to sell it to MrBeast though.

Pop Quiz: Answer

Sponsored by Retool

What gets logged?

const myObject = {};

const key = Symbol('key');

myObject[key] = 'this is the value for the key';

console.log(myObject[Symbol('key')]);
console.log(JSON.stringify(myObject));

1. undefined - The Symbol constructor creates a unique value, so the Symbol used to set the value of myObject[key] is not the same as the Symbol used to get the value of myObject[key].

2. {} - JSON.stringify ignores Symbol properties when stringifying an object.

This is useful for creating private properties on objects that can’t be accessed or modified outside of the object. You can read more about Symbols here.
