If you were passionate about gaming growing up, you’re probably no stranger to Connect-4, the wildly popular game that connects four single-colored discs in a lattice-like holder in front of your opponent. This course gives you the chance to relive those sweet childhood memories by mocking Connect 4 with React.

React, also known as React JS, is a powerful JavaScript library that is used to create custom and interactive user interfaces with UI components. Some of the most well-known examples of organizations using React for their frontend are Netflix, Facebook, and Airbnb. Developed and maintained by Meta alongside a community of independent developers, React remains free and open source. React is a component-based library built entirely on top of JavaScript, making it ideal for designing complex user interfaces. With React, developers can create encapsulated components that effectively manage their own state and render custom UI updates when data changes. For example, consider the auto-update feature you see on your Twitter feed or Facebook Like button. Here the UI component’s state changes on the page without requiring manual updating when the data is refreshed. This is just a small but powerful feature of React.


Through comprehensive hands-on projects, this course will teach you all the core React principles you need to know to become a proficient React developer. We’ll start with the tools needed to get started with React and instructions on how to build a Connect-4 gameboard. From there, we’ll dive into React OnClick Events, Passing Props, Destructing, React Children, and Passing Arguments. With a solid foundational understanding, students explore various techniques for designing game components, as well as dynamic classes and handling callbacks. Here we’ll explore inline, global, and dynamic styles combined with dynamic classes. Next we continue with the React State Hook, React Key Property and initialize the game module. Students then explore more intermediate concepts, including logical components for calculating winners, determining equivalence, and React lifecycle events. In the last module, we examined the implementation of AI for automatic movement suggestions and single player games.

In addition to the handy React module, we also provide a comprehensive overview of JavaScript for those who need a refresher. Here we start with an introduction to the Document Object Model (DOM), which defines the logical structure of an HTML document. From there, we’ll dive into JavaScript to demonstrate the various methods that can be used to manipulate DOM elements to add interactivity to static components. We’ll start from the basics, covering JavaScript layout and data output. From there we move on to variable declarations, arithmetic operations, operator precedence, data types, and objects. Now that the basics are covered, let’s move on to more complex operations that use arrays, conditionals, JavaScript comparison operators, Booleans, and loops. Here, students will learn to unleash the true power of JavaScript to produce different results based on user interaction. We explored using functions to efficiently process repetitive tasks and JavaScript events to process output based on actions and events. The unit ends with a hands-on project in which students apply their knowledge to create web-based photo galleries and background color changers.
