javascript - 根据另一个列表制作动态列表

Question

我有一个结构如下的列表

[{name:A,key:1},{name:B,key:2},{name:C,key:3}]

我想用这种结构创建一个列表，但要反转名称和键之间的数据:

[{name:1,key:A},{name:2,key:B},{name:3,key:C}]

我该怎么做？

Answer 1

你可以映射它

const data1 = [{name:"A",key:1},{name:"B",key:2},{name:"C",key:3}];

const data2 = data1.map(data=>{
    // if statement
 return {key: data.name, name: data.key}
});
