AngularJS - Why is ng-bind faster than expressions?

Question

From this question and this answer, it seems that using expressions will cause the value to be evaluated from scratch every time. But I\'ve searched the documentation and tutori

Answer 1

The major difference between ng-bind and {{}} is that ng-bind creates a watcher for variable passed to it(i.e. name as in above example), while curly brackets({{}}) will (store the entire expression in memory i.e. }perform dirty-checking and refreshing the expression in every digest cycle even if it is not required. ng-bind will only apply when the value passed is changing actually. for more details refer below link: http://www.ufthelp.com/2015/11/difference-between-and-ng-bind-in.html
