TypeScript 7.0 RC: Faster Than Your Excuses

Alright, listen up. It’s time for another round of “why the hell didn’t you do this years ago?” TypeScript 7.0 Release Candidate has landed, and the big damn headline is this: Microsoft rewrote the compiler in Go, and now it’s up to 10x faster. Yes, ten-fucking-times. Apparently, when you stop abusing JavaScript to compile JavaScript, shit magically improves.

The old TypeScript compiler was basically a bloated, wheezing mess that choked on large projects like an asthmatic hamster. Enter the new Go-based compiler, built to actually use your CPU cores instead of staring at them blankly. Builds are faster, incremental compiles are snappier, and memory usage doesn’t look like a crypto miner ran wild in your RAM. What a concept.

Microsoft claims this shiny new compiler keeps compatibility with existing TypeScript projects, so you don’t have to rewrite your whole pile of spaghetti code (this week, anyway). It’s still early days—this is a release candidate, not divine intervention—so some tooling and edge cases may lag behind. But for once, the performance promises don’t sound like total marketing bullshit.

In short: same TypeScript, less waiting, fewer fans spinning up like jet engines, and slightly fewer reasons to scream at your build pipeline. It’s not going to fix your garbage architecture or your coworker who commits directly to main, but at least the compiler won’t be the slowest asshole in the room anymore.

Sign-off: This reminds me of the time I replaced a “temporary” Perl script that took 40 minutes to run with a compiled binary and finished before my coffee cooled down. Everyone acted surprised. I called them idiots and went to lunch.
