    You can use filter function and check value with the index in both the array and then you can get the mismatched values from a.

    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);

    Here I used Javascript’s filter method to get the mismatched 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"]
