在下面的数组中，该值被javascript视为indexOf()方法中的第四个索引/位置。是"Mango"还是"Banana" ?

var fruits = ["Banana", "Orange", "Apple", "Mango", "Banana", "Orange", "Apple"];
var a = fruits.indexOf("Apple", 4);

这里有一个小工具可以使用:

var arr = ["Banana", "Orange", "Apple", "Mango", "Banana", "Orange", "Apple"]
var index = parseInt(prompt("Give an integer between 0 and " + (arr.length - 1)));
alert("At index: " + index + " we find: " + arr[index]);
for (var i = 0; i < arr.length; i++) {
  console.log(i, ":", arr[i]);
}
