Lets’s see an example of how collect.js works.

Example: In this example, we will see how to create new collection instance using Collect.js make() Function.

index.js

// Requiring module
const collect = require('collect.js')

// User defined collection
var myCollection = [1,2,3,4,5]

function make(items = []) {
    return new this.constructor(items);
}

// Creating collection object
const collection = collect(myCollection);

// Printing collection
console.log(collection.all());

// Make Function call
console.log(make([1,2,3]))

Run the index.js file using the following command:

node index.js

Output:

[ 1, 2, 3, 4, 5 ]
[ 1, 2, 3 ]
