Ask HN: When did you have with software the Aha moment?

[arrmn]

I was wondering when you had the last time an "Aha now all makes sense", "Aha now I understand why other people like it" when you were using some peace of software/library?

4 years ago, when I started my current job. Up to that point, I had been using Notepad++ for all my web development "IDE" needs. A coworker introduced me to VSCode, and I will never, ever go back, because why would I be that masochistic?

Turns out it’s all just lisp macros, or at least it should be.
