Answer 2

反应已更新，不包含const data = [ ['Apple', 'Orange', 'Banana', 'Pears', 'Peach'], [40, 35, 25, 58, 84], [2, 4, 4, 3, 1, 2], ['Red', 'Yellow', 'Green', 'Violet', 'Blue'] ]; let mapIdxToProp = new Map([[0, "name"],[1, "price"],[2, "quantity"],[3, "color"]]); let minLen = Math.min(...data.map(x => x.length)); let res = data.reduce((acc, arr, idx) => { arr.forEach((x, j) => { (j < minLen) && (acc[j] = acc[j] || {}, acc[j][mapIdxToProp.get(idx)] = x); }); return acc; }, []); console.log(res);。将propTypes中的import语句替换为以下导入：

GoogleSignIn.ios.js
