What is React Native?

React Native is a free tool made by Facebook for creating mobile apps that work on different types of devices. It uses JavaScript and React. React Native started in 2015 and quickly became popular with developers because it is efficient and flexible.

Developers can write their code once and use it on iOS and Android, saving time and reusing code. React Native makes it easy for developers who know JavaScript and React to build mobile apps without any extra learning.

One of the best things about it is that it quickly shows any changes you make to the code, so developers can work faster and better. React Native also has many extra tools and parts made by other people. This lets developers add new features and change their apps however they want.

React Native works really efficiently with native modules, so apps can run almost as fast as if they were native. It has a lot of people working on it, easy-to-understand instructions, and Facebook supports it. It keeps getting better and is useful for making high-quality apps for different types of phones.

Advantages of React Native

Advantages of React Native
  1. Good Performance

React Native is good for making mobile apps because it uses the same controls and features as the device, which makes the apps work well and run smoothly. This leads to a very good performance. It’s like it sneaks into a computer’s main parts and uses its functions to do separate tasks.

  1. Modular Design

The modular architecture in React Native helps developers release app updates more easily and promotes the reuse of modules, similar to web APIs. This helps things work better and also lets us use the code again. It separates different parts of your program into modules that can be easily changed.

  1. Hot Reloading

Changes you make to your code will automatically be applied without needing to restart the application. It allows developers to immediately see the changes they have made to the app’s code in a preview window. This quick feedback helps developers make changes to the app faster.

  1. Simplified App Updates

React Native’s Over-the-air updates (OTA) make it so you don’t have to make a new process for each update. The changes will be working when you open the app next time. So, updates download faster and easier, and you don’t even need to go to the app store.

  1. Low Cost Add-On Features

With React Native, you can add new things to your app without starting over. Developers can add new user interface parts to a current app, which makes it easier and cheaper to make the app do more things.
