Technical Training

Want to get trained in react.js , [login to view URL] , node.js , mongodb. I do know js(es6) btw i actually started learning these but stuck somewhere. So i want indepth knowledge in these topics like what is going on behind the scenes . If you can teach me in detail about these or atleast react,redux and node that will be great. I'll prefer offline teachings (saturdays and sundays) near chd, mohali , delhi or near these.
