AngularJS directives: scope isolation “=” and “@”

In this example I show you how to create AngularJS directives with an isolated scope, illustrating several ways to do it: “=”, “@”, true and false (default).


The code below creates 5 directives with different scope isolation settings to demonstrate how they works.

In order to understand the differences I really suggest you to use ngInspector (or Batarang), a cool Chrome extension to see the structure of the scope of your AngularJS applications (as shown in the image below and in the video at the end of the post).
