>Meh. Flaming about this is so exhausting given that the war was already fought and we know who the winner is.

I mean yeah its obvious that typescript had insufficient performance for the typescript compiler. They made a big public announcement about the rewrite to golang. It's pretty clear who the winner is.

>First, that's the typescript compiler, not typescript apps. And it was a ground-up rewrite effort (a very large one) with a specific eye toward improving the performance of the original, which was widely held to be sub-optimal for reasons entirely unrelated to implementation language.

The typescript compiler uses v8 as a runtime to run itself and it used to be written in typescript. It was probably one of the biggest typescript apps there is.

Here are some reasons why they chose golang over v8:

* the memory allocation patterns of a compiler were a poor fit for the v8 JIT * the runtime is restricted to a single thread * JITs have to make a tradeoff between startup time and how much time they spend optimizing generated code, AOT compilation can spend more time optimizing while having a faster startup time which is critical for a CLI application, where the JIT cost is paid every time the program is started

>Suffice it to say that, hell no, you can't just transpile your code to Go and expect it to run faster. We all know it doesn't work like that.

This is a straw man that nobody is proposing, but even a naive attempt would probably have some benefits, primarily relating to startup time and memory consumption.

Use Electron for the typescript compiler? Are you crazy? (note that ajross responded with this comment https://news.ycombinator.com/item?id=48170285)
