\u00cen baza de cod a platformei JavaScript Node.js s-a implementat o modificare care adaug\u0103 posibilitatea de a executa fi\u0219iere cu cod scris \u00een limbajul de programare TypeScript. Suportul pentru limbajul TypeScript se activeaz\u0103 prin op\u021biunea «—experimental-strip-types» \u0219i este limitat la eliminarea defini\u021biilor de tip specifice acestui limbaj, adic\u0103 transformarea codului surs\u0103 \u00een JavaScript \u00eenainte de execu\u021bie. Func\u021bionalit\u0103\u021bile TypeScript care nu sunt legate de descrierea tipurilor, cum ar fi spa\u021biile de nume, decoratoarele, propriet\u0103\u021bile parametrilor \u0219i tipurile enumerate (enum), nu sunt \u00eenc\u0103 suportate. Noua func\u021bionalitate poate fi testat\u0103 folosind versiunile nightly de ast\u0103zi ale Node.js 23. <\/p>\n

Pentru traducere este folosit compilatorul SWC (Speedy Web Compiler), scris \u00een limbajul Rust. Pentru a nu ad\u0103uga dependen\u021be suplimentare la Node.js, a fost folosit\u0103 implementarea compilatorului swc\/wasm-typescript, livrat\u0103 \u00een cod intermediar WebAssembly \u0219i deja utilizat\u0103 \u00een acelea\u0219i scopuri pe platforma Deno. Modificarea a fost ad\u0103ugat\u0103 ca r\u0103spuns la numeroasele cereri ale utilizatorilor de a implementa posibilitatea de a rula cod TypeScript f\u0103r\u0103 a instala \u00eenc\u0103rc\u0103toare externe \u0219i dependen\u021be adi\u021bionale. Pe platformele concurente Deno \u0219i Bun, suportul pentru TypeScript a fost implementat ini\u021bial. <\/p>\n

Diferen\u021ba cheie \u00eentre TypeScript \u0219i JavaScript este definirea explicit\u0103 a tipurilor. Tiparea static\u0103 ajut\u0103 la evitarea multor erori \u00een timpul dezvolt\u0103rii, permite utilizarea unor tehnici suplimentare de optimizare, simplific\u0103 depanarea \u0219i face codul mai u\u0219or de citit \u0219i mai simplu de \u00eentre\u021binut de c\u0103tre al\u021bi dezvoltatori. \u00cen implementarea ad\u0103ugat\u0103 \u00een Node.js, aceste capabilit\u0103\u021bi TypeScript sunt pierdute, deoarece \u00een timpul traducerii textelor surs\u0103 \u00een JavaScript, verificarea tipurilor nu se efectueaz\u0103.
