🤟 How We Migrated Our Rush.js Monorepo to Node Type Stripping
Since v23.6 (and in LTS since v22.18.0), Node has supported running (most) TypeScript code by stripping the types out first. The Calm team was excited about the potential for improving productivity and DX, and set a migration in process. Here’s a look at the challenges encountered and what the end results were.

Is there a difference between the previous code (red) and the new one (green) ?
Actually, there is 35second difference 😠
The previous code was, on every loop, creating a new object, always deallocating and reallocating memory, while the second example creates one object (a cache) and save each item into it.

If Linus Torvalds applied for a junior coding job today…
He’d get rejected.
He doesn’t have “5 years React experience.”
That’s how broken hiring has become. 😨

🤟 Eliminating JavaScript Cold Starts on AWS Lambda
Porffor is a rapidly developing ahead-of-time JavaScript compiler with a major benefit being extremely quick process launch times (think sub-millisecond). This is certainly more a taste of the future, and something to experiment with, rather than something you want to imminently deploy into production.
