.map()实现json对象的键名替换

let data = [
    {value: 8,label: '苹果'},
    {value: 6, label: '香蕉'},
    {value: 12, label: '葡萄'},
]
data = data.map(item => {
    return {
        name: item.label,
        price: item.value
    }
})
console.log(data) // [{name: "苹果", price: 8}, {name: "香蕉", price: 6}, {name: "葡萄", price: 12}]
