how to copy one array to another in javascript
const sheeps = ['Apple', 'Banana', 'Juice'];
// Old way
const cloneSheeps = sheeps.slice();
// ES6 way
const cloneSheepsES6 = [...sheeps];var numbers = [1,2,3,4,5];
var newNumbers = Object.assign([], numbers);// 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 () {}];
