The ngBind attribute tells Angular to replace the text content of the specified HTML element with the value of a given expression, and to
update the text content when the value of that expression changes.
means just ngBind会告诉angular去将你写的表达式替换成一个特殊的html元素.
And this 特殊的html元素 is the span with class,
Double curly brackets{{}}和ngBind是一样的,实际上是一个directive, there is only a slight difference in the scope of application
Thanks for the invitation. You can see it in the source code of angular https://github.com/angular/angular.js/blob/master/src/ng/compile.js#L1...
In fact, it is used to bind data to this "top text node"

The HTML value output by AngularJs ng-bind will definitely not be just 4. Otherwise, how to control the position of the output value?
aHow is the value of this variable assigned?
Generally $scope.a=4;
The output result of {{a}} is 4.
