Why does Angular have Jsonp?

Question

Angular

Good afternoon!
Why does AngularJS (1) support Jsonp requests?
After all, Cors appeared only in IE9, and Angular does not support < IE9

Answer 1

1) Jsonp has been around since the earliest versions of angular
2) angular at the time of release of version 1.0 had support for ie8 at least
3) since angular 1.x cannot have significant backward compatibility violations - you can’t just delete jsonp.

Answer 2

jsonp to make requests to other sites
