Here's a fun little perf win I managed over the weekend on eslint-plugin-react: github.com/jsx-eslint/eslint…
This shaves off about 1/3 of the time spent linting TypeScript/JavaScript in the @getsentry repo - about 70 seconds!

instead of leetcode we need 5 rounds of interviews to see if you can understand the legacy service that's failing on a decomisioned cloud api with no documentation and you have to find the engineer who first wrote part of the code so he can point you to a 5 years old jira ticket

💡 TIL about Compute Pressure API
This permits observing compute pressure on things such as:
- CPU
- GPU
- thermals
Pressure levels: critical > serious > fair > nominal
This just landed in Chrome 125
This could be useful under the hood for Concurrent React? 🤔

OH MY GOD IT'S HAPPENING
In TS 5.5, type predicates will be inferred automatically from functions that return a narrowing statement.
No more 'val is string' to force TypeScript's hand.
@danvdk, I can't believe you got it merged. Incredible work.

Put up my second #TypeScript PR! It allows the type checker to infer "type predicates" when a function returns a boolean that's tied to a refinement on one of its parameters. I have no idea if it'll be accepted, but I sure learned a lot implementing it!

By the end of 2024, you’ll likely never need these APIs again:
• useMemo, useCallback, memo → React Compiler
• forwardRef → ref is a prop
• React.lazy → RSC, promise-as-child
• useContext → use(Context)
• throw promise → use(promise)
• <Context.Provider> → <Context>
