React Class Property Syntax and Plugin Configuration
Class Property Syntax:
- In the classsyntax branch, class properties are defined using class property syntax.
- Arrow functions are properly contextualized and class members (methods and properties) are like regular variables inside the class block, but without preceding const or let.
- To reference these members, this can still be used.
Plugin Configuration:
- To enable this, install @babel/plugin-proposal-class-properties with yarn add @babel/plugin-proposal-class-properties -D.
- Configure webpack to use this plugin by adding the following rule to webpack.config.js: `{ test: /.js$/, exclude: /node_modules/, use: { loader: { ... }, options: { plugins: ['@babel/plugin-proposal-class-properties'] } } }
Summary:
This change introduces class property syntax in React, allowing for more concise and expressive class definitions.
