Angular2 two-way data binding

Question

I know Angular2 doesn\'t have two-way data binding but is there a way to mimick the two-way data binding behavior from Angular1.x?

Answer 1

Here is a simple plunker which demonstrates one way, two way and event driven approaches in action according to Angular2 2.0.0-beta.17

Two-way Event and property

One way property

Event driven

We can dig Angular docs for more

[UPDATE 1/26/2020]

Since Angular2 beta libs are removed from project CDN ! above plnkr link doesn't work anymore.

Use below new plnkr Angular 6+ page , I ported previous page to NPMJS, new angular edition and new plnkr!
