Quick Answer
Angular rendering pipeline: TypeScript compilation, template compilation (AOT), change detection runs top-down from root component, dirty components are re-rendered, Virtual DOM diffing (Ivy's incremental DOM approach), and actual DOM is patched with only the changes. Ivy (Angular 9+) generates more efficient, tree-shakable component code compared to the old ViewEngine.
Answer
The rendering pipeline steps:
Change detection runs to identify data changes.
Angular updates DOM nodes via compiled instructions.
Directive inputs + lifecycle hooks run.
Browser recalculates styles and layout.
Paint + render occurs.
Angular optimizes minimal DOM updates for performance.
