Just using tsc to compile a hello world with 7 tokens takes over a second in my experience. Sure, most of that is initialization, but compare that to the C and C++ world, where GCC spends tens of milliseconds at most compiling hello world.

Hot reloading _helps_, but it's definitely an issue that javascript tooling spends seconds on tasks other languages' tooling spends tens or hundreds of milliseconds on. (The issue isn't just limited to tsc either; just starting the build system can take a decent amount of time with webpack, while make or cmake starts in milliseconds.)
