reactNative

React Native is a well-known mobile application development framework that allows developers to create rich, cross-platform mobile application UI using reusable components. It's ideal for building mobile applications and supports multi-platform reusable code, pre-built components, and a rich UI. Most well-known social media platforms, such as Facebook and Instagram, have been built using React Native. 

In this course, you’ll start with a brief introduction to React Native and then cover various built-in components of React Native categorized into different categories such as basic, user interface, user interaction, and list view components. Next, you’ll learn about concepts such as application styling, navigation, Hooks, state management, and database management. You’ll find interactive quizzes and challenges throughout the course to test your understanding.

By the end of this course, you’ll be able to develop mobile applications and kickstart your journey as a React Native developer.

Getting Started with Mobile App Development with React Native

Application programming needs excellent debugging support. Debugging a React Native application can be tricky. However, with the right tools and techniques, we can quickly identify and fix problems. There are several tools available that can help developers debug React Native applications. Let's explore some of the best tools for debugging React Native applications.

# Reactotron

**Reactotron** is a desktop application for monitoring and debugging React Native applications. It provides a powerful set of tools for debugging, including a timeline view for tracking the performance of our application, a network inspector for monitoring network requests, and a console for logging messages and debugging code. 

# Flipper

**Flipper** is a desktop application that provides a range of debugging and performance tools for React Native applications. It supports debugging with Chrome Developer Tools and allows us to profile and improve our application's performance. It also provides a timeline view for tracking the performance of our application and a network inspector for monitoring network requests. 

# React Native debugger

The **React Native debugger** is a powerful debugging tool for React Native applications. It's based on the official debugger and Chrome Developer Tools and has features like hot reloading, element inspector, network inspector, and more. With the React Native debugger, we can set breakpoints, inspect variables, and take advantage of powerful debugging features that simplify debugging.

# Remote debugging

**Remote debugging** is a powerful way to debug React Native applications. It allows us to debug the application on a device that is connected to our computer. With remote debugging, we can set breakpoints and view the application's #key# logcat: A command-line tool that allows access to messages from applications and services running on an Android device. #key# to identify potential issues. We can also use remote debugging to analyze performance issues, such as slow loading times or stuttering animations.

# Visual Studio Code

**Visual Studio Code** is a popular code editor for React Native. Visual Studio Code has an integrated debugger extension named React Native Tools that we can use to debug React Native applications. The debugger allows us to set breakpoints, step through code, and inspect variables. Visual Studio Code also has an integrated terminal that we can use to run React Native commands. This makes it easy to run `npm` commands or launch the application on a device.

# Chrome Developer Tools

React Native uses the **Chrome Developer Tools** to debug JavaScript code remotely. However, cross-hierarchy debugging is not supported with this tool. With the Chrome Developer Tools, we can set breakpoints and view the debug log of our React Native application. We can also use the Chrome Developer Tools to profile our application and identify potential performance issues.

# React developer tools

The **React developer tools** are a browser extension that can be used to debug React applications. It provides features such as a component hierarchy and the ability to inspect props and states. The React developer tools can be used to debug React Native applications. It allows us to inspect the component tree and state, view the navigation tree, and set breakpoints.

# Console logs

One of the most useful tools in a developer’s toolkit is the `console.log` statement, which provides the ability to log messages to the console for debugging purposes.
The `console.log` statement is a powerful and simple tool that can help to debug errors. It is a function that prints a message to the console window of the browser (in the case of a web application) or the terminal window (in the case of a mobile application). For example, if an application crashes, the `console.log` statement can be used to log what is happening in the application at the time of the crash. This information can be used to pinpoint the source of the error and fix it.
