I learned front-end scripting laungages from manumits...praveen sir gives the live example for each concept and try to explain in different way to make sure we understand the concepts... I will say manumits is the best place to learn different technologies :)??
I had enrolled for JS / Jquery / AngularJS course.. Praveen Sir is very much good with his teaching and has deep knowledge in the topics. Takes into consideration your understanding and explains accordingly with simple and easy to understand examples. No second thoughts ! Only Manumits !
