Is it safe to delete yarn.lock from my project's directory?

[adamalston]

1. Why is the yarn.lock file generated? I have never run a yarn ... command in the initialization or setup of my app.

I searched for answers online and came across this discussion: https://stackoverflow.com/questions/51048173/switch-to-npm-for-create-react-app

If it's an existing project you can just remove yarn.lock and continue using it with npm.

2. I am using npm to manage packages for my project. Is yarn necessary at all?
3. If it is not necessary, can I delete it without affecting how React compiles and builds my project?

If you don't know what it is, you probably shouldn't delete it. https://classic.yarnpkg.com/en/docs/yarn-lock/ gives some info about it. You most likely installed yarn and CRA sees that and uses it.
