如何在react native中添加或给出Id和一些随机数到JSON中的键(Id)

Question

My Data Look Like This =

[
{"name":"Wooden Furniture"},
{"name":"Office Furniture"},
{"name":"Kitchen Furniture"},
{"name":"Modular Office Furniture"}
]

我想把它转换成这样=

[
{"name":"Wooden Furniture","id":"someRandomNumber"},
{"name":"Office Furniture","id":"someRandomNumber"},
{"name":"Kitchen Furniture","id":"someRandomNumber"},
{"name":"Modular Office Furniture","id":"someRandomNumber"}
]

我只是想在每个对象中添加Id:SomeRandomNumber

Answer 1

使用Array#map:

const arr = [{"name":"Wooden Furniture"}, {"name":"Office Furniture"}, {"name":"Kitchen Furniture"}, {"name":"Modular Office Furniture"} ];
const res = arr.map(o => ({ ...o, id: "SomeRandomNumber" }));
console.log(res);
