Notable Changes

Corepack

Node.js now includes Corepack, a script that acts as a bridge between Node.js projects and the package managers they are intended to be used with during development.
In practical terms, Corepack will let you use Yarn and pnpm without having to install them – just like what currently happens with npm, which is shipped in Node.js by default.
Please head over to the Corepack documentation page for more information on how to use it.
