The SWC (Speedy Web Compiler) written in Rust is used for the transpilation. To avoid adding additional dependencies to Node.js, the swc\/wasm-typescript compiler representation is utilized, delivered in WebAssembly bytecode and already used for the same purposes in the Deno platform. This change was made in response to numerous user requests to enable the execution of TypeScript code without installing external loaders and additional dependencies. Competing platforms Deno and Bun have initially implemented TypeScript support. <\/p>\n
The key difference between TypeScript and JavaScript is the explicit type definition. Static typing helps avoid many errors during development, allows for additional optimization techniques, simplifies debugging, and makes the code more readable and easier to modify and maintain by external developers. In the implementation added to Node.js, these TypeScript capabilities are lost, as type checking is not performed during the transpilation of the source texts into JavaScript. \n Forr\u00e1s: opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"
