+
+Stand alone shallowCompare for use in libraries that support shouldComponentUpdate
+
+## API
+
+`shallowCompare(instance, nextProps, nextState)`
+
+ - instance (_component instance_) - the component's instance (`this`)
+ - nextProps (_object_) - the next props
+ - nextState (_object_) - the next state
+ 
+## Example
+```javascript
+class Foo extends Component {
+  constructor (props) {
+    super(props);
+    this.state = { color: 'blue' }
+  }
+
+  shouldComponentUpdate (nextProps, nextState) {
+    return shallowCompare(this, nextProps, nextState)
+  }
+
+  render () {
+    return (
+      <div>{this.state.color}</div>
+    )
+  }
+}
+```
