For RN >= 0.57 please look at https://github.com/blankg/rn-webview-bridge-sample-new/blob/master/resources/index.html. Provides a sample implementation for sending and receiving messages to and from the React-Native WebView (using postMessage/onMessage WebView API).
/**
* Created by Guy Blank on 3/9/17.
*
* This is a sample provides an API to send & receive messages to and from the React-Native WebView (using postMessage/onMessage WebView API).
* A sample project that uses the bridge is available here https://github.com/blankg/rn-webview-bridge-sample
*
* webViewBridge.send('functionToInvoke', {mydata: 'test'}, function(){console.log('success')},function(){console.log('error')});
*
* The API is designed to be similar to the Cordova exec API so migration to it should be almost seamless.
* The API also provides solution to a React-Native WebView bug in iOS which causes sending consecutive postMessage calls to override each other.

How to recover a git branch you accidentally deleted

UPDATE: A better way! (August 2015)

As pointed out by @johntyree in the comments, using git reflog is easier and more reliable. Thanks for the suggestion!

 $ git reflog

3970d09 HEAD@{2}: checkout: moving from b-fix-build to develop
1ed7510 HEAD@{3}: commit: got everything working the way I want
