Sure! Here's an example of a simple racing game implemented as a single HTML file using JavaScript:
This racing game creates a simple road using a canvas element and a car represented by a red square. The car can be controlled using the left and right arrow keys on a smartphone's keyboard. The game starts upon the DOMContentLoaded event, and the car's position is updated based on the user's input. The car moves horizontally within the road boundaries, and the game continuously redraws the canvas to display the car's movement.
Please note that this example is just a basic foundation for a racing game. You can enhance it further by adding more features such as obstacles, opponents, lap counting, and scoring.
