Il supporto per TypeScript si attiva tramite l'opzione &#171;&#8212;experimental-strip-types&#187; ed \u00e8 limitato alla rimozione delle definizioni di tipo specifiche di questo linguaggio, cio\u00e8 alla conversione del codice sorgente in JavaScript prima dell'esecuzione. Le funzionalit\u00e0 di TypeScript non correlate alla descrizione dei tipi, come i namespace, i decoratori, le propriet\u00e0 dei parametri e i tipi enumerabili (enum), non sono ancora supportate. \u00c8 possibile testare questa nuova funzionalit\u00e0 utilizzando le attuali versioni notturne di Node.js 23.      <\/p>\n<p>Per la transpilazione \u00e8 stato utilizzato il compilatore SWC (Speedy Web Compiler), scritto in Rust. Per evitare di aggiungere dipendenze extra a Node.js, \u00e8 stato utilizzato il frontend del compilatore swc\/wasm-typescript, fornito in codice intermedio WebAssembly e gi\u00e0 utilizzato per gli stessi scopi nella piattaforma Deno. Questa modifica \u00e8 stata aggiunta in risposta a numerose richieste degli utenti di implementare la possibilit\u00e0 di eseguire codice TypeScript senza installare caricamenti esterni e dipendenze aggiuntive. Nelle piattaforme competitor Deno e Bun, il supporto per TypeScript \u00e8 stato implementato fin dall'inizio.    <\/p>\n<p>La principale differenza tra TypeScript e JavaScript \u00e8 la definizione esplicita dei tipi. La tipizzazione statica consente di evitare molti errori durante lo sviluppo, offre la possibilit\u00e0 di utilizzare tecniche di ottimizzazione aggiuntive, semplifica il debug e rende il codice pi\u00f9 leggibile e facile da modificare e mantenere da parte di sviluppatori terzi. Nella realizzazione aggiunta in Node.js, queste funzionalit\u00e0 di TypeScript vengono perse, poich\u00e9 durante la transpilazione dei testi sorgenti in JavaScript non viene effettuato alcun controllo dei tipi.<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=61607\">opennet.ru<\/a>
