4 javascript developers goes to bar aaand we have a new framework.

That's because everyone who does anything with JS calls everything a framework. Bitch this is not a framework, it's a logging class. You shouldn't have made one, there are enough out there. And what does it need a twenty-step-build-pipeline for? Only so your async function works in IE3, where it will never actually be used? And why do you have 45 dependencies? So you can import a package, so that you save a single "if"?

.... Just kidding, I love JavaScript :D
