V k\u00f3dovej b\u00e1ze JavaScript platformy Node.js sa zavedie zmena, ktor\u00e1 prid\u00e1va mo\u017enos\u0165 sp\u00fa\u0161\u0165ania s\u00faborov s k\u00f3dmi v programovacom jazyku TypeScript.

Na preklad sa pou\u017e\u00edva kompil\u00e1tor SWC (Speedy Web Compiler), nap\u00edsan\u00fd v jazyku Rust.
