var a=["a","b","c","d"];
var b=["b","a","c","d"];

您可以使用筛选函数并检查两个数组中索引的值，然后从中获取不匹配的值。

var a = ["a", "b", "c", "d"];
var b = ["b", "a", "c", "d"];

var c = a.filter(function (item, index) {
  return item !== b[index];
});

console.log(c);

这里我使用Javascript的filter方法来获取不匹配的Array。

const a = ["a","b","c","d"];
const b = ["b","a","c","d"];

const mismatchedArr = a.filter((aItem,index) => aItem !== b[index]);
console.log(mismatchedArr); //Prints ["a","b"]
