About this course

Building real projects is the most effective way to transition from reading about code to actually writing it. This text-based course guides you through the process of creating a fully functional, interactive Minesweeper game using standard web technologies. By working through this project, you will solidify your understanding of the Document Object Model (DOM), event handling, and game logic state management. What you will learn: 1. Understand foundational web concepts and initialize your project structure with clean HTML5 semantic elements. 2. Design a responsive grid layout using modern CSS Grid and Flexbox techniques. 3. Implement game state logic in JavaScript to track cell coordinates and mine locations. 4. Apply DOM manipulation techniques to dynamically render the game board in real time. 5. Master event listeners to handle left-clicks for revealing cells and right-clicks for flags. 6. Practice algorithmic thinking by implementing a recursive reveal function for empty cells. 7. Organize your JavaScript code using modern ES6+ features for better readability. The course begins with foundational concepts, establishing your project structure and styling the game board, before stepping through the core JavaScript logic and algorithms. This course is designed for beginner web developers who have a basic understanding of HTML, CSS, and JavaScript and want to build practical project experience.
