Yarn is faster than npm. We can move package manager from Npm to Yarn for JavaScript now.

npm install npm ci yarn
install without cache (without node_modules) 3m 3m 1ms
install with cache (without node_modules) 1m 18s 30s
install with cache (with node_modules) 54s 21s 2s
install without internet (with node_modules) - - 2s
