ES6语法将数组内每个对象的checked属性去掉

// 要求： // 现有数组对象： let arr = [ {featureId: 1, featureContent: ‘全新未用’, checked: ‘0’}, {featureId: 2, featureContent: ‘验货面付’, checked: ‘0’}, {featureId: 3, featureContent: ‘快递包邮’, checked: ‘0’}, {featureId: 4, featureContent: ‘保修期内’, checked: ‘0’}, {featureId: 5, featureContent: ‘专柜正品’, checked: ‘0’}, {featureId: 6, featureContent: ‘有发票’, checked: ‘0’} ]; // 要求使用ES6语法将数组内每个对象的checked属性去掉。

右边是一个括号的话说明返回的是一个值(对象)，就是括号里面的值，如果直接写{name, sex}会被认为是块语句

({ name, sex }) => ({ name, sex }) 相当于 ({ name, sex }) => { return { name, sex } }
