NPM installation warnings

Ubuntu 20.04.3 LTS, npm version 7.24.0, node version v14.17.6, Python 3.8.10

I'm new to the npm/node/vue universe, any pointers on how to remedy these npm install warnings would be appreciated:

npm WARN deprecated babel-eslint@7.2.3: babel-eslint is now @babel/eslint-parser. This package will no longer receive updates.
npm WARN deprecated eslint-loader@1.9.0: This loader has been deprecated. Please use eslint-webpack-plugin
npm WARN deprecated extract-text-webpack-plugin@3.0.2: Deprecated. Please use https://github.com/webpack-contrib/mini-css-extract-plugin
npm WARN deprecated html-webpack-plugin@2.30.1: out of support
npm WARN deprecated browserslist@2.11.3: Browserslist 2 could fail on reading Browserslist >3.0 config used in other tools.
npm WARN deprecated core-js@2.6.12: core-js@<3.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Please, upgrade your dependencies to the actual version of core-js.
npm WARN deprecated querystring@0.2.1: The querystring API is considered Legacy. new code should use the URLSearchParams API instead.
npm WARN deprecated flatten@1.0.3: flatten is deprecated in favor of utility frameworks such as lodash.
npm WARN deprecated browserslist@1.7.7: Browserslist 2 could fail on reading Browserslist >3.0 config used in other tools.
npm WARN deprecated circular-json@0.3.3: CircularJSON is in maintenance only, flatted is its successor.
npm WARN deprecated chokidar@2.1.8: Chokidar 2 will break on node v14+. Upgrade to chokidar 3 with 15x less dependencies.
npm WARN deprecated querystring@0.2.0: The querystring API is considered Legacy. new code should use the URLSearchParams API instead.
npm WARN deprecated fsevents@1.2.13: fsevents 1 will break on node v14+ and could be using insecure binaries. Upgrade to fsevents 2.
npm WARN deprecated resolve-url@0.2.1: https://github.com/lydell/resolve-url#deprecated
npm WARN deprecated urix@0.1.0: Please see https://github.com/lydell/urix#deprecated

Thank you for using core-js ( https://github.com/zloirock/core-js ) for polyfilling JavaScript standard library!

The project needs your help! Please consider supporting of core-js on Open Collective or Patreon:

Also, the author of core-js ( https://github.com/zloirock ) is looking for a good job -)
