What is regularInterceptedExpression in angular?

angularjs performance angularjs-digest

Found this on AngularJs Docs, hope this can help.

Following scenarios could cause this error.

When you declare a local scope property using = in a directive. This will create a interceptedExpression.
method calls in the view

Angular Tip: We should avoid method calls in the view whenever possible, since they run on every $digest loop.

Thanks,
