javascript deep clone array code example
Example 1: deep clone array in javascript
const numbers = [1, [2], [3, [4]], 5];
// Using JavaScript
JSON.parse(JSON.stringify(numbers));
// Using Lodash
_.cloneDeep(numbers);
Example 2: copy object array javascript
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?)
Example 3: js clone deep
// only works with pure JSON data (bool, numbers, strings, arrays, nested
// objects; No functions).
var obj2 = JSON.parse(JSON.stringify(obj));
// works with everything, requires lodash library, faster than previous answer
var obj2 = _.cloneDeep(obj, true);
// shallow copy
var obj2 = Object.assign({}, obj);
