REDUX INTERVIEW QUESTIONS ANDROID
What's the Challenges with React Native?Īns: Working across separate iOS and Android codebases is challenging. This means you can use the same editor and propagate it to both the iOS simulator and Android emulator at the same time.Īirbnb, Box, Facebook, GitHub, Google, Instagram, LinkedIn, Microsoft, Pinterest, Pixar Animation Studios, Twitter, Uber, and WhatsApp all use React code. Now this project has been released on Github, developers can use a single workflow to develop for iOS and Android. This business logic was already written in JavaScript, and the team knew it wouldn't be efficient to build it all again in Objective-C to do it again in Java for Android.
REDUX INTERVIEW QUESTIONS FOR ANDROID
Three product engineers familiar with React set about to create an app for Android and predicted problems with the logic necessary to understand differing time zones, date formats, currencies and ad formats across the world. React Native has only recently been proven in production and building a new app based on the framework carried some risk. Ads manager lets businesses that advertise on the social network manage their accounts and create new adverts. How did Facebook write React Native for Android?Īns: The first cross-platform React Native app - ads manager - was developed by the London-based dev team, who were in the US to announce the Android release yesterday evening. "poke on it to see if it was still working every day at 10am," mobile engineering manager Bryan O'Sullivan joked earlier this year.

It's a considerable development from when the fledgling startup copied Facebook code on Harvard University's server for releases and, Over ten years' it has scaled to serve one billion users, thousands of developers and three major platforms - iOS, Android and Web.

If every engineer Facebook hires already knows how to write in React Native, they have a running start.įacebook has a culture of maturing its development. Developers want a challenge, and a sense of giving back - and Facebook wants a large pool of talented engineers to pick its employees from. Web engineers across the world are quick to point out a bug in the code for free.ĭeveloping open source projects helps keep Facebook one of the most coveted companies to work for. Keeping a businesses infrastructure under-wraps has commercial advantages, especially when your technology is your business model.īut the developer community is loyal to those who open up. Why open source?Īns: "If we work together in the open, we can advance the state of technology together," Facebook said in a blog post yesterday evening.Īltruism aside, opting to open source code is a tricky decision.
Now just one developer can write across different mobile operating systems.įacebook opened up React in 2013 and has been using its proprietary React Native code for iOS app development for over a year. Engineers won't have to build the same app for iOS and for Android from scratch - reusing the code across each operating system.Īndroid and iOS have very different codebases and startups and businesses often struggle to hire - or afford- engineers for both. React Native helps developers reuse code across the web and on mobile. Native app creation means writing apps for a specific operating system. Ans: React Native is the next generation of React - a Javascript code library developed by Facebook and Instagram, which was released on Github in 2013.
