In Hungarian, mizujs means "what's up", and it's often shortened to mizu, so, having a mizu.js JavaScript library would be a pretty cool name (for us who understand Hungarian).

Maybe it'd feel weird for a native speaker to have something named "Water", but it does sound cool.

But that's also related to another project of mine, matcha (which is a kind of tea) which is a semantic css stylesheet.

Both were designed as a mini-ecosystem, kind like how you would put tea in your water

it'd be as weird as mizu if it were just named cha/ocha

I mean, we have stuff called “windows”, “word”…

“Water” is as good a name as any other. Congrats on your work, I look forward to testing it out this weekend!

The Japanese name makes it cool and fancy :).
