如何基于索引数组获取值数组?

我有一组两个数组.一个包含一些水果值作为字符串，另一个包含一些随机数.在这里，我认为数字数组是水果数组的索引.给定索引数组中的数字，如何获得新的水果数组?

I have a set of two arrays. One contains some fruit values as strings, the other one contains some random numbers. Here I considered the number arrays are the indexes of the fruits array. How to get a new array of fruits given the numbers in the index array?

示例代码:

var resultArr = [];
var fruitier = ["apple", "orange", "grapes", "pineapple", "fig", "banana", "jackfruit", "pomegranate"];
var indexArr = [0, 2, 4];

输出:

resultArr = ["apple", "grapes", "fig"];
