Both are amazing package managers and allow you to do things In the speed of light and develop almost on the fly. I’ve used both but I have to say I love NPM more.. I would say just form the ease of use I’ve had and the fact that I’ve created almost every project thus far using it. BUT, I will say yarn 2.0 if you haven’t checked it out yet is starting to look like a winner now.. with a big thing for me being zero-installs. You can now use yarn without installs of dependencies and from a cache. If that cache changes it just caches again upon a few yarn commands. This is huge. It will make your projects faster and more lightweight. I want to know what feature your most looking forward to and if you like NPM or yarn more? Comment below!
