1. Native JavaScript implementation
var array1 = ["a", "b"];
var array2 = ["c", "d"];
After merging, I want it to look like this:
var array= [ "a", "b", "c", < ;span class="string" style="color:rgb(221,17,68)">"d"];
Can be used
arr1.concat(arr2);
2. Jquery implementation
$.merge(array1,array2);
console.log($.unique(array1));
