AngularJS Batarang - What are interceptedExpressions?

Question

I'm currently using the AngularJS 1.3.0 stable build and the Batarang Chrome extension. In the watch tree I notice that under many of my scopes there's something called "interceptedExpression". What is that or what scenarios create an interceptedExpression?

Answer 1

• What is interceptedExpression?

  interceptedExpression is a function returned by $parse.

• Why its called interceptedExpression in Batarang?

  Because the function declared inside angular source code is a named function called interceptedExpression.

• What scenarios create an interceptedExpression?

  One of the scenarios I know is when you declare a local scope property using = in a directive. This will create a interceptedExpression record in batarang. See angular src here.

what about regularInterceptedExpression? – Quintilla

is there a way to reduce this is the case of the directives using =? – Locust

or a oneTimeInterceptedExpression – Prolongation

I think the only way to reduce it is by reducing the number of properties nested within $scope in your controller. – Township
