I wonder if TypeScript is really more popular or if its growth is due to LLM's using it. If it is, it would mean that we are producing about 20% more code Year on Year.

This chart is a great resource for understanding time and space complexity for different array sorting algorithms. I was trying to create my own version to study, but this one is so much clearer and more comprehensive.

Spent the last two weeks chasing down a single bug 🐛
20 iterations later, it finally works.
Longest debug session of my life (so far)—so relieved it’s over! 🎉

Using AI for unit testing has been a game changer.
It took some time to set up, but now the LLM has a deep understanding of how the app works — and plenty of guardrails to keep it from going off the rails.
Highly recommend it!
