So react provides the JSX (JavaScript eXtension) syntax that allows you to write HTML code in JS.render () { return div>Hello {this.props.name}div>;}What is JSXJSX provides an XML-like extension based on the ECMAScript. JSX and HTML are a bit like, but there are different places. For example, the class attribute in HTML is classname in JSX. Other different places, you can refer to the FB HTML Tags vs. Reac

React + Webpack construction and packaging optimization, reactwebpack This article describes how to optimize React + Webpack construction and packaging. The details are as follows: Use babel-react-optimize to optimize the React code Check unused libraries and remove import references Package the class libraries as needed, such as lodash and echart. Lodash can be optimized using babel-plugin-lodash. Note tha

provides a powerful way to process the frontend build steps. Loader can convert files from different languages (such as TypeScript) to JavaScript, or convert Inline images to data URLs. Loader even allows you to directly import CSS files in the JavaScript module! From this, we can see that the powerful function of loader is analyzed as follows: The role of conversion. All files used for development are converted into html, css, js, img, and other required formats for webpage loading. The c
