Module Installation: Install collect.js module using the following command from the root directory of your project:
npm install collect.js
The below example illustrates the take() method in collect.js:
Example 1: Filename: index.js
Javascript
// Requiring the module const collect = require('collect.js');Â Â Â Â Â // Sample array let arr = [2, 4, 5, 6, 7, 8, 9];Â Â Â Â Â // Creating collection const collection = collect(arr);Â Â Â // Function call const result = collection.take(5) Â Â // Printing the result object let newObject = result.all(); console.log(newObject); |
Run the index.js file using the following command:
node index.js
Output:
[2, 4, 5, 6, 7]
Example 2: Filename: index.js
Javascript
// Requiring the module const collect = require('collect.js');Â Â Â Â Â // Sample array let arr = ['a', 'b', 'c', -3, 4, -6, 7];Â Â Â Â Â // Creating collection const collection = collect(arr);Â Â Â // Function call const result = collection.take(-3) Â Â // Printing the result object let newObject = result.all(); console.log(newObject); |
Run the index.js file using the following command:
node index.js
Output:
