Depends on the workload.
I spent a few grand building a new machine with a 24-core CPU. And, while my gcc Docker builds are MUCH faster, the core Angular app still builds a few seconds slower than on my years old MacBook Pro. Even with all of my libraries split into atoms, built with Turbo, and other optimizations.
6-10 seconds to see a CSS change make its way from the editor to the browser is excruciating after a few hours, days, weeks, months, and years.
Web development is crazy. Went from a Java/C codebase to a webdev company using TS. The latter would take minutes to build. The former would build in seconds and you could run a simulated backtest before the web app would be ready.
It blew my mind. Truly this is more complicated than trading software.
For this reason the TypeScript 7 compiler will be written in Go.
That won't help Angular, because its design doesn't lend itself to such speedups. The compiler produces a change detector function for every reactive structure such a class field, so the final app is necessarily huge.
No ccache?
A lot of this seems to have gotten a lot better with esbuild for me, at least, and maybe tsgo will be another big speed-up once it's done...
