I'm not sure if I could do much of anything as a developer if I didn't use third-party packages I didn't fully understand.

I suppose I could spend much of my day carefully vetting dependencies... but what about dependencies of dependencies?

So you don't use 3rd party packages? Because the moment you use one you don't fully understand it --that comes with time. You can't magically know every nuance about a package before you start using it. I haven't looked at the code at all for momentjs or the internals of Vue, there's still a lot I don't know about their api's but doesn't mean I still don't get value out of using them.

I take it you don’t use any 3rd party vue/angular/react components?

There’s certainly a place for telerik—only UIs I suppose.
