Q:

javascript clone array of objects

const numbers = [1, [2], [3, [4]], 5];

// Using JavaScript
JSON.parse(JSON.stringify(numbers));

// Using Lodash
_.cloneDeep(numbers);

var ar = ["apple","banana","canaple"];
var bar = Array.from(ar);
alert(bar[1]); // alerts 'banana'

// Notes: this is for in In ES6, works for an object of arrays too! 
// (May not be applicable for deep-copy situations?)

var sheep=[
{"height":20,"name":"Melvin"},
{"height":18,"name":"Betsy"}
];
var clonedSheep=JSON.parse(JSON.stringify(sheep)); //clone array of objects
//note: cloning like this will not work with some complex objects such as:  Date(), undefined, Infinity
// For complex objects try: lodash's cloneDeep() method or angularJS angular.copy() method
