Honestly? They probably don't know how, or that's just not part of the JS culture. I've met a lot of JS-only developers, and most probably don't even know what ANSI escape sequences are, let alone how to work with them. The lack of basic computer knowledge from the JS ecosystem is shocking. I don't expect this to poll well in Peoria, as it were, but this has been my consistent observation.

Laziness; and people’s infatuation for dependency trees, especially those in the Node.js & JavaScript ecosystems.

JS devs will do anything to avoid this.
