i know typescript used write angular2, makes better choice wants angular2, when @ babel looks typescript. i noticed many known companies stick babel. some questions: what advantages have on each other? which make them better or worse choice project/developer? what major differences between them , make them unique? typescript superset of javascript compiles down plain javascript (es3+). main goal of typescript enable developers leverage excellent static typing capabilities. suitable large applications benefit features like: type annotations & type inference. generics. interfaces, enums, namespaces, modules , classes (the latter 2 available in es6). safe refactoring. as far aware, babel "transpiles" newer ecmascript features down format supported older ecmascript environments. suitable developers want write plain javascript using newer language features.

we implementing new website used alongside existing system. current system uses ie8 in setting new site, jquery2.0 has been used. if downgrade jquery 1.10, lose of functionality? the blog ( http://blog.jquery.com/2013/07/03/jquery-1-10-2-and-2-0-3-released/ ) isn't clear. is going complex job downgrade? no. jquery 1.9+ , 2.0+ same newer browsers. difference between 1.9x , (including 1.10) , 2.0 , 2.0+ branch gets rid of code provides support legacy browsers. newer browsers, shouldn't see difference (except possibly faster jquery because of smaller size.)
