What do you mean? I commented in the first place because I was surprised that Kite uses JS+Python, a unique combination for an email client from what I've seen (which is not a lot). I'm not interested, nor do I have the capabilities to make an email client (I can reskin RoundCube or use Gmail) or any app, for now. But the reason I want to learn JavaScript, as well as Python, is because I want to get a feel of how both work, and not get binned in the "uses JavaScript for everything" category, which seems to be a bad thing :-). It was hard to decide on a language to learn by myself, C and Java are recommended, but look hard to begin with. I don't want to get discouraged early on. JavaScript is always needed (monetary opportunities) and rather easy, Python also seems easy to learn and very flexible. Ruby was my other choice, but I feel like I'm going to get overwhelmed studying them all at once.
