mingca / WebViewBridge.js
Created May 4, 2018 14:06 — forked from blankg/WebViewBridge.js
Provides a sample implementation for sending and receiving messages to and from the React-Native WebView (using postMessage/onMessage WebView API).
View WebViewBridge.js
/**
* 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).
*
* 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.

View Even Fibonacci Numbers
# "Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:
# 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...
# By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms."
# Instructions:
# Construct a solution using Ruby that could be incorporated into a larger project. Solutions will be evaluated for readability, testability, and extensibility.
# Calculate sum of even-valued terms in fibonacci
