react怎么筛选数组，返回新的数组

Question

var arr =[
    {op: "danmaku", text: "大师傅是对方", uid: "1", name: "看看"},
    {op: "danmaku", text: "三顿饭地方发", uid: "1", name: "流量"},
    {op: "danmaku", text: "徐州持续催促", uid: "2", name: "看看"},
    {op: "danmaku", text: "大师傅是对方", uid: "1", name: "看看"},
    {op: "danmaku", text: "大是否都是的", uid: "1", name: "看看"}];

//有很多项的数据，怎么筛选原数组的数据，新数组只返回text和uid

    [{text: "大师傅是对方", uid: "1"},
    {text: "三顿饭地方发", uid: "1"},
    {text: "徐州持续催促", uid: "2"},
    {text: "大师傅是对方", uid: "1"},
    {text: "大是否都是的", uid: "1"}];

Answer 1

let arr =[{op: "danmaku", text: "大师傅是对方", uid: "1", name: "看看"},
    {op: "danmaku", text: "三顿饭地方发", uid: "1", name: "流量"},
    {op: "danmaku", text: "徐州持续催促", uid: "2", name: "看看"},
    {op: "danmaku", text: "大师傅是对方", uid: "1", name: "看看"},
    {op: "danmaku", text: "大是否都是的", uid: "1", name: "看看"}];
let _arr = arr.map((ele,index)=>{
    return {
        text:ele.text,
        uid:ele.uid
    }
    
})

console.log(_arr);
