js copy element from object array code example
Example 1: javascript clone array of object
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
Example 2: js deep copy array
const numbers = [1, [2], [3, [4]], 5];
// Using JavaScript
JSON.parse(JSON.stringify(numbers));
// Using Lodash
_.cloneDeep(numbers);
