var arr = "abcdef".split(''); // creates an array from a string

var str = arr.join(''); // creates a string from that above array

From String to Array you can Use split() Method

var str = "How are you doing today?";
var res = str.split(" ");

console.log(res); // How,are,you,doing,today? it will print

From Array to String you can use Join() method or toString() Method

If you want do it manually, without any JavaScript methods. Try the below

String to Array

var str = "STRING";
var arr = [];
for(int i=0; i<=str.length; i++)
    arr[i] = str.charAt(i);

Array to String

var str = "";
var arr = ["S","T","R","I","G"];
for(int i=0; i<=arr.length; i++)
    str +=arr.charAt(i);
