"You could build a very complex UI with Ext.JS back in 2010 with a lot less code and very little time" I have not encountered a more complex and verbose library than ExtJS. I would never in a million years say "very little time" with ExtJS. I did not enjoy my time with it at all. And that was a whole lot of time, since it took forever to do the simplest of things.
