react && redux

connect

@connect(
    ({global, login, investment}) // state 解构
    =>
    ({...global,...investment,...login}) // props 解构
)
// 将state绑定到props的counter
const mapStateToProps = (state)=> {
    return {
        counter: state
    }
};
export default connect(mapStateToProps, mapDispatchToProps)(Counter)
// 即
(state)=>({counter: state})
export default connect((state)=>({counter: state}), mapDispatchToProps)(Counter)

prop-types

// 开发环境推荐使用，由于不具有强制约束的能力，生产环境建议使用插件优化掉
Greeting.propTypes = {
  name: PropTypes.string,
  children: PropTypes.element.isRequired
};
Greeting.defaultProps = {
  name: 'Stranger'
};
