ng-style or style attribute with binding? Which is better? Which is faster? What is the difference?

Question

I am optimizing my large application. I am confused between following two approach, please help to decide which one is faster.

Inline style attributes

Answer 1

Since you are optimizing your considerably large application, performance is definitely under question and I think ngStyle performs better as it sets up watch on the model and will update the view only if the model has changed.

So I would go with ngStyle or onceStyle depending on your scenario:

Using {{}} will make Angular update the binding every digest cycle, even if the value has not changed.
