// join an array together into a string
// array for the .join() method
let numbers = [3, 1, 6]
let string = numbers.join(', ') // returns '3, 1, 6'
// Also works the same just for an array of STRINGS
const elements = ['Sun', 'Earth', 'Moon'];
console.log(elements.join());
// output: "Sun,Earth,Moon"
console.log(elements.join(''));
// output: "SunEarthMoon"
console.log(elements.join('-'));
// output: "Sun-Earth-Moon"var array = ["Joe", "Kevin", "Peter"];
array.join(); // "Joe,Kevin,Peter"
array.join("-"); // "Joe-Kevin-Peter"
array.join(""); // "JoeKevinPeter"
array.join(". "); // "Joe. Kevin. Peter"//turns array to string
const elements = ['Fire', 'Air', 'Water'];
console.log(elements.join());
// expected output: "Fire,Air,Water"
console.log(elements.join(''));
// expected output: "FireAirWater"
console.log(elements.join('-'));
// expected output: "Fire-Air-Water"
//The join() method also joins all array elements into a string.
const fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.join(" * ");
// result : Banana * Orange * Apple * Mango
