💡 "We had six months left" — the Tailwind story + new TanStack library

Tailwind laid off 75% of their engineering team this week. Adam Wathan said they had six months of runway left before making the call. The reason? AI made their product less essential — LLMs can now generate and explain Tailwind classes better than their docs could sell. It's a stark reminder that disruption isn't just about who writes the code. But enough doom and gloom — this week I've also got a CSS deep dive, practical JavaScript tutorials, and some genuinely useful learning resources. Here's what's worth your time.

And please share some love this weeks sponsors:

"We Had Six Months Left" — Adam Wathan on Tailwind's AI Crisis (30 min)
