If you want to merge the arrays, you can use the following code:

var array1 = ["Vijendra", "Singh"];

var array2 = ["Singh", "Shakya"];


If you want to remove the duplicates, you can prefer the below code:

function arrayUnique(array) {

    var a = array.concat();

    for(var i=0; i<a.length; ++i) {

        for(var j=i+1; j<a.length; ++j) {

            if(a[i] === a[j])

                a.splice(j--, 1);



    return a;


var array1 = ["Vijendra","Singh"];

var array2 = ["Singh", "Shakya"];

    // Merges both arrays and gets unique items

var array3 = arrayUnique(array1.concat(array2));

I hope this will help.
