給定一個(gè)數(shù)組。我想創(chuàng)建一個(gè)遞歸函數(shù)，它循環(huán)遍歷 arr 并將鍵/值對(duì)推送到一個(gè)新數(shù)組 (arr2) 中，如下所示：var arr2 = []function recursive(arr) // function gets executed arr2 //will return the array with arrays[    [ mike, 22]    [ robert, 12]    [ roger, 44]    [ peter, 28]    [ ralph, 67]]到目前為止，我有這段代碼，但它將對(duì)象推入 arr2，而不是數(shù)組！var arr =[{name:'mike', age:22},{name:'robert', age:12},{name:'roger', age:44},{name:'peter', age:28},{name:'Ralph', age:67}]var arr2 = []function recursive(arr) {  if (Array.isArray(arr)) {    arr.forEach(function(object) {      arr2.push(object)    })  }}recursive(arr)console.log(arr2)我該如何解決？
