react native was released by Facebook in 2015, he is The Native version of React aims to develop client interfaces and logic through JS, saving costs and time, and achieving the purpose of one code that can be used by multiple terminals. After 2 years of development, the performance of RN has been greatly improved and is now comparable to the native version. , the community thrives.
React Native takes a different approach to hybrid mobile app development. It does not generate native UI components, but is based on React. React Native is a JavaScript library used to build web-based interactive interfaces, so it will have a richer UI experience and can also well call the UI of the underlying framework. use. React Native has become a popular mobile development technology. It provides a powerful framework for building native cross-platform mobile applications using JavaScript. When needed, we can also use Objective-C, Swift or Java to write native code to bridge.
The role of react native
React Native uses Javascript language, JSX similar to HTML, and CSS to develop mobile applications, so technicians familiar with Web front-end development only It takes very little learning to get into mobile app development.
React Native enables you to get a completely consistent development experience based on Javascript and React and build world-class native APPs.
React Native enables you to write native mobile applications using only JavaScript. It is consistent with React in terms of design principles and uses a declarative component mechanism to build a rich and colorful user interface.
React Native focuses on improving the development efficiency of multi-platform development - you only need to learn once and write for any platform.
React Native combines the advantages of web applications and Native applications, and can use JavaScript to develop iOS and Android native applications. Use React in JavaScript to abstract the native UI components of the operating system and replace DOM elements for rendering, etc.

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.
