It offers an event-driven environment where non-blocking I/O has been an important principle. For more information about Node.js, please refer to this page. The development team has versions 18.13.0a version with extra long support, and 19.4.0 released. The most important changes made in both versions are summarized for you below.

Node v18.13.0 (LTS) notable changes

Add support for externally shared js builtins

By default Node.js is built so that all dependencies are bundled into the Node.js binary itself. Some Node.js distributions prefer to manage dependencies externally. There are existing build options that allow dependencies with native code to be externalized. This commit adds additional options so that dependencies with JavaScript code (including WASM) can also be externalized. This addition does not affect binaries shipped by the Node.js project but will allow other distributions to externalize additional dependencies when needed. Contributed by Michael Dawson in #44376

Introduce File

The File class is part of the FileAPI. It can be used anywhere a Blob can, for example in URL.createObjectURL and FormData. It contains two properties that Blobs do not have: lastModified, the last time the file was modified in ms, and name, the name of the file. Contributed by Khafra in #45139

Support function mocking on Node.js test runner
