Ember is nice, but it is a gigantic framework with a steep learning curve, and very heavy on the wire (lots of kb). I used it at my last job. I'm using mithril

Ember is nice, but it is a gigantic framework with a steep learning curve, and very heavy on the wire (lots of kb). I used it at my last job. I'm using mithril.js right now for a side project, with basic ES5 and no build tools. Mithril has a tiny API but still offers surprising amounts of power. I'm enjoying the simplicity of everything. It's been nice spending way less cognitive energy to understand how all the pieces fit together =) I may have to add some tooling in when I deploy the finished project, but I'm going to keep it as minimal as possible.
