In this article, you will learn how to deep copy an array using Lodash.
Let’s say you have an array named ‘a’ with elements ‘1, 2, 3, 4’.
// Import Lodash library
import _ from "lodash";
var a = [1, 2, 3, 4];
In order to deep copy an array using Lodash, you can use the _.cloneDeep() method.
// Import Lodash library
import _ from "lodash";
var a = [1, 2, 3, 4];
// Create a deep copy of the previous array
var b = _.cloneDeep(a);
// Change the first element of array 'b' to 9
b[0] = 9;
console.log(a);
// => [1, 2, 3, 4]
console.log(b);
// => [9, 2, 3, 4]
Note: The _.cloneDeep() method functions by creating a fully independent yet exact copy of supplied values.
