Let me take you on a visual introduction to what big O notation is in my new blog post: samwho.dev/big-o.
With big O notation you can better understand how algorithms will perform in practice, finding orders of magnitude improvements often with very simple changes to your code.

I figured out how to add the official Playwright browser automation MCP to Claude Code. Run this before you start "claude":
claude mcp add playwright npx '@playwright/mcp@latest'
Now Claude Code can use a Chrome browser directly!
Here's my TIL: til.simonwillison.net/claude-code/...

🎉 Introducing my upcoming third course, Whimsical Animations!
This course will teach you how to build top-tier animations and interactions using a variety of techniques. ✨
You can join the waitlist on the course’s brand-new site, which is the most ridiculous thing I’ve built in quite some time:

I am happy to share that I’ve successfully completed The Joy of React course from @joshwcomeau.com
Before I didn’t feel confident of my React skills, despite having years of experience. Josh’s course helped me build a great foundation I will use for the rest of my career!

Friends! I've decided to go back to FTE and need your help finding good opportunities.
I want to work on web apps again on a great team.
I can do product or platform work, am great at React & TS, but happy to grow outside that bubble for the right thing.
DMs are open!
