                                    /* Copying arrays or parts of arrays in JavaScript */

var fruit = ["apple", "banana", "fig"]; // Define initial array.
console.log(fruit); // ["apple", "banana", "fig"]

// Copy an entire array using .slice()
var fruit2 = fruit.slice(); 
console.log(fruit2); // ["apple", "banana", "fig"]

// Copy only two array indicies rather than all three
// From index 0 (inclusive) to index 2 (noninclusive)
var fruit3 = fruit.slice(0,2); 
console.log(fruit3); // ["apple", "banana"]

                                    // this is for array with complex object
var countries = [
  {name: 'USA', population: '300M'}, 
  {name: 'China', population: '1.6B'}
];

var newCountries = JSON.parse(JSON.stringify(countries));

                                    // 1) Array of literal-values (boolean, number, string) 
const type1 = [true, 1, "true"];

// 2) Array of literal-structures (array, object)
const type2 = [[], {}];

// 3) Array of prototype-objects (function)
const type3 = [function () {}, function () {}];
