5 JavaScript Style Guides — Including AirBnB, GitHub, & Google

  • 5 JavaScript Style Guides — Including AirBnB, GitHub,  GoogleLearn to code like a GooglerWhether you’re just starting to learn JavaScript, or getting ready for your big interview with AirBnB, here are 5 style guides that can help you write cleaner code.What the heck is a style guide?A style guide is a set of standards…
  • As you read through these guides, you can get an idea for how code is written at the respective companies.Why do we need style guides?For one main reason: Everyone writes code differently.
  • That’s all fine and dandy as long as we each work on our code.
  • But what happens when you have 10, 100, or even 1,000 developers all working on the same codebase?
  • Style guides are created so new developers can get up to speed on a code base quickly, and then write code that other developers can understand quickly and easily!

React and React Native [Book]

Adam Boduch's

  • Use React and React Native to build applications for desktop browsers, mobile browsers, and even as native mobile apps

    Who This Book Is For

    This book is written for any JavaScript developer—beginner or expert—who wants to start learning how to put both of Facebook’s UI libraries to work.

  • What You Will Learn

    React and React Native allow you to build cross-platform desktop and mobile applications using Facebook’s innovative UI libraries.

  • The first part shows you how to start crafting composable UIs using React, from rendering with JSX and creating reusable components through to routing and creating isomorphic applications that run on Node.
  • We then move on to showing you how to take the concepts of React and apply them to building Native UIs using React Native.
  • Split into three major sections to help organize your learning, this hands-on, code-first book will help you get up to speed with React and React Native—the UI framework that powers Netflix, Yahoo, and Facebook.

Rapid cross-platform mobile development with React Native

  • We can avoid the need for lots of upfront planning and naturally fall into certain conventions and patterns of data fetching and state management.
  • import React, { Component } from ‘react’
  • React Native exposes the Platform module, which detects the platform on which the app is currently running.
  • Sometimes we may need to diverge our application flow by platform in order to perform the appropriate action, but often it’s as simple as swapping some values around based on the current platform.
  • Platform-specific extensions allow us to write a separate file for each platform, e.g. button.ios.js and button.android.js .

How React Native helped us ship a cross-platform mobile app in 8 weeks.
