PS: swc and esbuild aren't good example, because most of the speed improvements comes from the fact that they are just stripping TS-specific syntaxes to generate JS code.

Also tsc is slow, sure, but only for the first run. Enabling `incremental` flag or using watch mode with `--transpile-only` usually brings compile time under 100ms, Making it practically indistinguishable from SWC or ESBuild.
