Does AngularJS redraw the DOM?

Question

css

When angular applies filters - does it re-render the DOM or swap already existing elements?

Answer 1

what? filters are twitched on every $digest cycle. If the filter changes its value, then the DOM changes. The DOM changes - regardless of how it changes, the page or part of it is redrawn.
Or clarify your question. I suspect that you are interested in cases of a combination of ngRepeat and filters for collections. If instead of "redrawing" you mean creating nodes, then ngRepeat tries to use existing nodes. Specify.
