Angular lazy one-time binding for expressions

Question

AngularJS has a new feature since the version 1.3.0-beta.10: the \"lazy one-time binding\".

Simple expressions can be prefixed with ::, telling angular

Answer 1

Yes. You can prefix every expressions with ::, even the ones in ngIf or ngClass:

<div ng-if="::(user.isSomething && user.isSomethingElse)"></div>
<div ng-class="::{classNameFoo: user.isSomething}"></div>

Actually, the code simply checks that the two first characters in the expression are : in order to activate the one-time binding (and then removes them, thus the parenthesis aren't even needed). Everything else remains the same.
