+Observable Slim was originally built as part of the **[Nimbly](https://github.com/elliotnb/nimbly)** JS framework where it assists with state management, state mutation triggers and one-way data binding. Observerable Slim was separated out from Nimbly in order to serve use cases outside of the scope of the **[Nimbly](https://github.com/elliotnb/nimbly)** framework.

+The `create` method is the starting point for using Observable Slim. It is invoked to create a new ES6 Proxy whose changes we can observe. The `create` method accepts three parameters:
 
 1. `target` - Object, required, plain JavaScript object that we want to observe for changes.
 2. `domDelay` - Boolean, required, if true, then Observable Slim will batch up observed changes to `target` on a 10ms delay (via `setTimeout`). If false, then `observer` will be immediately invoked after each individual change made to `target`. It is helpful to set `domDelay` to `true` when your `observer` function makes DOM manipulations (fewer DOM redraws means better performance).
