its very easy to append new value to array in JavaScript
var d=["i","am"];
d[1]="expert";
d.push("developer");
console.log(d);//["i", "expert", "developer"]
one can use .push function to push to array which will append at last of array
d.push("developer");
it will add developer in the list at end of array
and one can reset or add new by use of index of array
d[1]="expert";
it will add value expert to index -1 if not exist index or reset it with value expert.

you can use push function to append new value to array
var a = [];
a.push(1, 2, 3);
console.log(a);
you can use multiple argument to push to append multiple value to array in JavaScript .

one can use spread syntax to append to array with push function
var a = [1];
var anew = [3,4,5];
a.push(...anew)
console.log(a);//[1, 3, 4, 5]
if you try to push directly array to another array . it push array instead of its value and become multidimensional array
var a = [1];
var anew = [3,4,5];
a.push(anew)
console.log(a);//[1, Array[3]]
so please note the difference between push array to array and push array 's value to another array .
