Is react software?

react is not software, but a web development framework. It is a JavaScript library used to build user interfaces, making it easy to create interactive UIs; react component logic is written in JavaScript instead of templates, so users can Easily pass data around your application and decouple state from the DOM.

react is not software, but a web development framework.

React is a declarative, efficient and flexible JavaScript library for building user interfaces. React allows you to combine short, independent code snippets into complex UI interfaces. These code snippets are called "components".

React is an open source JavaScript library that provides views of data rendered into HTML. React views are typically rendered using components that contain other components specified in custom HTML tags. React provides programmers with a model in which child components cannot directly affect outer components, efficient updates to HTML documents when data changes, and clean separation between components in modern single-page applications.

React makes creating interactive UIs a breeze. Design concise views for every state in your app so React can efficiently update and render components correctly when data changes. Component logic is written in JavaScript rather than templates, so you can easily pass data around your app and keep state separate from the DOM.

Advantages of using react

1. React is very fast

It does not directly operate on the DOM, but introduces a virtual DOM Concept, placed between JavaScript logic and the actual DOM, with good performance.

reactjs defines a set of dom models in the form of variables. All operations and conversions are directly in the variables. This reduces the need to operate the real dom. The performance is really high. It is essentially different from the mainstream MVC framework. It does not Dealing with dom.

2. Cross-browser compatibility

Virtual DOM helps us solve cross-browser problems. It provides us with a standardized API, which is no problem even in IE8.

3. Everything is component:

The code is more modular, it is easier to reuse the code, and the maintainability is high.

4. One-way data flow

In fact, the core content of reactjs is data binding. The so-called data binding means that as long as some server-side data is bound to the front-end page, developers Just focus on realizing the business

5. Isomorphic, pure javascript

Because the search engine crawler program relies on server-side response rather than JavaScript execution, pre-rendering your application has Helps with search engine optimization.

6. Good compatibility

For example, use RequireJS for loading and packaging, while Browserify and Webpack are suitable for building large applications. They make those difficult tasks less daunting.
