The React Context API allows us to make data globally available. We could also do this by passing down props, but this isn't very efficient…
If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?
In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.
Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.
Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.
The popularity of React Native comes from its advantages. Some of its advantages are as follows:
Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.
React Native is very close to native. Consider the following aspects as described on the React Native website:
Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

In this article, you will learn what are hooks in React JS? and when to use react hooks? React JS is developed by Facebook in the year 2013. There are many students and the new developers who have confusion between react and hooks in react. Well, it is not different, react is a programming language and hooks is a function which is used in react programming language.

Hello! After writing two articles on useState and useEffect, today I want to write about Context in React. The purpose of writing these articles is to transfer the core concepts of hooks to beginners who are afraid of moving on and leave class-based components behind. Of course I’m not saying that class components aren’t good BUT would you drive an old car when you own a new S-Class Mercedes? Surely not! So this article is going to examine the benefits of Context, its usages, and different ways of implementations.
This article is the first part of my two-part series about Context. In part one we will review the basic concepts of context and a basic implementation and in the next part we’ll go straight to hooks.
We’re going to build a very small application which shows a list of favorite football players. It contains 3 components: our Navbar, PlayerList and ThemeToggler. We’re going to use context to handle our app’s theme (Dark/Light).
“Version 1.0.0” of my “context-playground” repo in GitHub covers this article’s contents.

You should know HOCs concept and state managing in react. That’s all!
Every react application includes some data and this data should flow in the application. Our data appears in our app as props or states. Consider an application, in which you want to show your favorite football players and teams. By using useState you can save your players array in PlayerList component and map over them to render a PlayerItem component for every player. So, you have to pass player data down by props. Consider a simple components hierarchy in below image:
Every thing looks nice! But things get messy when you want to pass some props from App.js to the TeamItem component! Yes, it’s two layers only but what if there were five layers between App.js and your component? Do you want to pass your data as a prop for five times?
Another challenge in our application is when we want to get some data from our PlayerForm component and pass it to TeamList! What should we do? React documents says:
“In a typical React application, data is passed top-down (parent to child) via props, but this can be cumbersome for certain types of props (e.g. locale preference, UI theme) that are required by many components within an application. Context provides a way to share values like these between components without having to explicitly pass a prop through every level of the tree.”
So, trust me. When you have a global variable that should be shared in your app and when you pass a prop 3 times down, consider using React Context.
