Support for detecting and being notified when an object is mutated.
An observable is a way to be notified of a continuous stream of events over time.
Some suggested uses for this library:
- Observe objects for changes, and log when a change occurs
- Optimize for observable collections in your own APIs and libraries instead of diffing
- Implement simple data-binding by listening to streams
You may want to look at the former TC39 proposal Observe.observe, which was deprecated.
Usage
There are two general ways to detect changes:
- Listen to
Observable.changesand be notified when an object changes - Use
Differ.diffto determine changes between two objects
