MindMap

Superset of Iterable: Exploring Set Operations

In this lab, you'll learn how to use the Set constructor and the Array.prototype.every() method to determine if one iterable is a superset of another. Discover how to create a function that checks if the first iterable contains all the elements of the second iterable, excluding any duplicates. This lab will deepen your understanding of working with sets in JavaScript. 👨‍💻 Superset of Iterable Lab

Implementing Caesar Cipher in JavaScript

Dive into the world of cryptography and learn how to implement the Caesar cipher, a simple encryption algorithm that shifts each letter of a given string by a certain number of positions down the alphabet. Explore string manipulation and array methods to encrypt and decrypt messages with this classic technique. 🔒 Implementing Caesar Cipher Lab

Weighted Random Sampling in JavaScript

Discover a practical implementation of a weighted sample function in JavaScript. This lab will teach you how to use Array methods such as reduce() and findIndex() along with Math.random() to generate random elements from an array, with probabilities assigned to each element based on the provided weights. 🎲 Weighted Random Sampling Lab

Fruit Matching Game with HTML, CSS, JavaScript

Put your front-end skills to the test by creating a simple 'Fruit for Fun' game using HTML, CSS, and JavaScript. In this project, you'll learn how to build a game board and implement the logic to match pairs of fruit images by clicking on the squares. 🍎 Fruit Matching Game Lab

Check if Arrays Have Same Contents

Explore how to check if two arrays have the same contents in JavaScript. You'll create a function that takes in two arrays and returns true if they contain the same elements, regardless of order, and false otherwise. Utilize a combination of Set, for...of loop, and Array.prototype.filter() to achieve this functionality. 🔍 Check if Arrays Have Same Contents Lab
