How to learn Angular 2

Question

i have to learn angular 2 quickly. now most of the company looking for a person who will develop UI with angular2 and use web api as service layer. hence i do not know angular 1 event then facing problem to learn angular 2 because i feel angular2 is not very easy to pick up.

 

i try to read few basic tutorial for angular2 but really do not understand well. i also saw people are generating code for angular2 with type script but i do not know type script too.

 

so anyone who using typescript to generate ng2 code then please guide me that how do i learn typescript ?

 

do i need to at all learn typescript from scratch or i can jump on to typescript for angular2 ?

 

please guide me in such a way as a result i can learn and develop apps with angular2 with typescript. thanks a lot.
