So I have built this web project using nodejs and expressjs at backend and angularjs in frontend. I have heard that javascript is a dagger as sharp at back as it is at front. If used improperly might lead to poorly performing app. I used jshint to check my syntax practices. But as I an pretty new to angularjs, I might not have used good conventions for my application. Is there any kind of service to check the speed of my project? or some place to help me guide through good practices of angularjs, and the to figure out, if any, bad practices that I have used?
