React Native has come a long way and Blue_sky is a testament that choosing this tech (or another cross-platform one like Flutter) is sensible for many startups over starting native.
Blue_sky is on iOS and Android, performance is excellent, and built by 1 engineer (!!)

Another Black Friday Cyber Monday (BFCM) weekend done and dusted!
We achieved 99.999+% uptime while averaging 3 Terabytes per minute of egress traffic across our infrastructure.
That’s 4.3 Petabytes per day! 🤯
Check out the thread for more awesome performance stats 🧵👇
Set your git config's push.autoSetupRemote to true and thank me later
(This will create a new upstream branch for your local branch automatically if it doesn't exist yet. No more "current branch xy has no upstream branch" errors on git push, yeah!)
There are 16 hooks in React 😏 😈
And I bet you never used this one: useSyncExternalStore()
Used internally in state management libs, like Redux
But have you ever thought about using it in your own app code?
💡 It could be useful & even prevent some React re-renders

Writing a dead-simple chat input field in React Native is surprisingly hard.
The naive solution:
- TextInput + button
- Button sends the text then clears TextInput
If you try this, you'll find several things are broken.
We finally launched react-native-bignumber! 🥳
It's a pure C++ implementation of a BigNumber type, exposed through JSI. 🔥
It brings much better performance to crypto apps and can even be used as a drop-in-replacement for BN.js to boost popular libs like ethers or elliptic! ⚡️

Do you like `useReducer`? Then you might like `useWorkerizedReducer` which runs the reducer in a worker. This allows you to place long-running, blocking logic inside a reducer.

I just spent ~4 hours investigating an "eats-all-the-gigabytes" memory leak in JavaScript and the solution turned out to be:
```diff
-arr.map(myFunction)
+arr.map(x => myFunction(x))
```
Because `map` passes 3 args: item, index, thisObj. Friends, be careful.

I can 100% see this as a big trend in 2022. It's just a darn nice way to size type.
Always messed with iOS message sending animation. Made it with Reanimated by @swmansion. They released v2.3 recently and Layout Animations works perfectly.
"I tell people to learn to code the same reason why I'm sure, in the 1600s or 1700s, it was good advice to tell people to learn to read and to write ... I think coding is just the new literacy."
