What are Advantages of using ES/TS syntax with AngularJs 1.x and Angular Js Material 1? As far I know I feel this will be helpful for Angular 2/4 upgradation
Is there any disadvantages of using Vanilla JS syntax with AngularJs 1.x and Angular Js Material 1.
Using TS will probably make it easier to upgrade to Angular (2+). Other than that, there are no particular benefits in using ES6/TS over Vanilla JS for AngularJS specifically. There are the general benefits (and tradeoffs) of using ES6/TS over Vanilla JS. There will be no AngularJS specific problems encountered whereas using TS/ES will make life easier though for organizing code, Code understandability and so on.. as said here and here.
