How to use Lodash _.toArray() Method In Javascript
Lodash is an JavaScript library that allows us to use the _.toArray() method which accepets a value and convert it to an array.
NOTE: To use this approach, you need to install the lodash library into your local system using the npm i lodash command.
Syntax:
const arrayName = _.toArray(setName);
Example: The below code implements the _.toArray() method of the lodash library to convert a set into an array.
// Requiring the lodash library
const _ = require("lodash");
let set = new Set(['welcome', 'to', 'GFG']);
console.log('Set Elements: ', set);
// Use of _.toArray() method
console.log('Array Elements: ', _.toArray(set));
Output:
Set Elements: Set(3) { 'welcome', 'to', 'GFG' }
Array Elements: [ 'welcome', 'to', 'GFG' ]
