I highly recommend reading this: https://github.com/zloirock/core-js/blob/master/docs/2023-02-14-so-whats-next.md

core-js@3.39.0 postinstall F:\gitlab\hello-world\node_modules\core-js
node -e "try{require('./postinstall')}catch(e){}"

puppeteer@23.11.1 postinstall F:\gitlab\hello-world\node_modules\puppeteer
node install.mjs

F:\gitlab\hello-world\node_modules\puppeteer\install.mjs:34
const {downloadBrowsers} = await importInstaller();
