A JavaScript library for building user interfaces

React simplifies the creation of interactive UI. If you design a simple view for each state in your application, React effectively renews and renders the correct component when the data changes.

We do not assume about the remaining technology stack. Therefore, you can develop new functions with React without rewriting the existing code.

The React component implements a render () method that takes input data and returns what it displays. In this example we use JSX with syntax like XML. The input data passed to the component can be accessed via render () via this.props.

JSX is optional and does not require React. Use Babel REPL to check the raw JavaScript code generated by the JSX compilation step.

Using props and status, we can combine small Todo apps. In this example, we use state to track the current item list and the text entered by the user. Event handlers look like inline, but are collected and implemented using event delegation.

React is very flexible and provides hooks to interact with other libraries and frameworks. In this example, we will use a temporary external Markdown library to convert its value in real time.

Instead, first look at the value proposition of the framework. React: A JavaScript library for building a complex user interface with a virtual DOM and a one-way data stream. Is this the way for you to do something more easily? Please check the homepage example. Your reply is "Wow, this solved the problem I encountered". Otherwise, you will have a hard time learning it. These examples are particularly useful. It seems to be difficult to build a list application to do at the front end? Did it end? try it. Please try using the technology you know. Please try to make it enough for you to use it. It will be very difficult. Please look forward to React after proceeding with it. It might make more sense. Then try building the same application with React for comparison.

React is a JavaScript library for building the user interface at the top of the list. React simplifies the creation of interactive UI. When designing a simple view of each state in the application, React effectively renews and renders the correct component when the data changes. Declaration view makes code easier to understand, easier to understand, and easier to debug. Babel is a compiler for writing next generation JavaScript. Babel is a community driven tool useful for writing code with the latest version of JavaScript. If your supported environment does not natively support certain features, Babel will help you compile these features into supported versions.
