Doesn't TypeScript get compiled into JavaScript? I thought TSC actually does a compilation, hence the name, TypeScriptCompiler? But anyway, this also exists for PHP. Psalm (https://psalm.dev/ https://psalm.dev/) or PHPStan (https://github.com/phpstan/phpstan https://github.com/phpstan/phpstan) both offer static type checking.

TS tries to keep syntax the same as JS. So tsc usually is just stripping types and, depending on settings, transpiling newer JS features to older versions.

  That's still called compiling, regardless if the thing it compiles into is similar or not.

    Well then PHP has opcache compiling.
