Zeta.js is such an impressive JavaScript library. I'm blown away. The examples where you can load a document in less than ten lines, amazing. Then, change colors of all cells in less than ten lines, amazing.
I'm also blown away that there is a gulp file in the repository. That's a blast from the past.
I'm still working with stuff using grunt (most certainly not my choice). gulp is not that bad as a generic task runner, though the last thing I'd use it for these days is to build JS artifacts.
