急求！！！！请问这种es6的写法是叫什么写法万分感谢

Question

请问大神们这种是什么写法呢'delete'(state,{payload:id})reducers:{'delete'(state,{payload:id}){returnstate.filter(item=>item.id!==id);},}

Answer 1

{payload:id}是对象解构赋值，具体参考解构赋值MDN而'delete'仅仅是对象属性名，事实上，对象的所有属性名都会被转为String如果你指的是'delete'(state,{payload:id}){}这种函数写法的话，则可以参考方法的定义MDN
