React-ions

Changes in Angular do not trigger a full re-render. The thing the author is trying to point out is that changes trigger a digest cycle and a digest cycle can (in some situations, not all) take a long time to figure out what has changed. But, once it figures out what has changed, it will only change those specific elements in the DOM.

At the end of the day, what we are talking about is Angular 1.x is not as efficient as React at figuring out what to modify in the DOM.

However, just be aware that this will all change in Angular2 where you can use an immutable data structure (just like React) or observable (if the situation warrants it) to quickly figure out what DOM updates need to occur. Read here for more:
