Example 1: js array to string
var myArray = ['no','u'];
var myString = myArray.toString();
Example 2: array to string javascript
var cars = ["Volvo", "BMW", "Audi", "Chevrolet"];
console.log(cars.toString());
//Output: Volvo,BMW,Audi,Chevrolet
Example 3: transform array to string js
//Use array.join(separator) //
const myArray = [1, 2, 3, 4, 5, 6];
console.log(a.join('/'));
//output : 1/2/3/4/5/6
const myArray = ['g', 'o', 'o', 'g', 'l', 'e'];
console.log(a.join(''));
//output : 'google'
