Our Commentary ​

Wow, what a week for JavaScript! Babel 8.0 finally going ESM-only after eight years is a huge, long-awaited step. And TypeScript 7.0 RC with 10x faster builds? That's not just an improvement; that's a game-changer for large projects. Deno Desktop also feels like a serious contender in the desktop app space, offering a compelling alternative to Electron. We're seeing foundational tools making massive leaps, and it's genuinely exciting. I'm particularly hyped for the TypeScript speedup; compile times can be a real drag.
