Make Random Decisions with a Spin Wheel Spin wheel decision maker — add options and spin to make a random choice with animation.

The tool's core functionality relies on the HTML5 Canvas element, which is used to render the spinning wheel. The `drawWheel` function, called repeatedly using `requestAnimationFrame`, updates the canvas with a new frame of the animation. This function uses the `arc()` and `fill()` methods to draw each slice of the wheel, with colors chosen from the `WHEEL_COLORS` array. The `useRef` hook is used to store a reference to the canvas element, allowing it to be accessed and updated efficiently.

When the user clicks the "SPIN!" button, the tool initiates a 4-second animation using `requestAnimationFrame`. During this time, the wheel's rotation is calculated using an ease-out cubic function, which ensures a smooth deceleration effect. The winner of the spin is predetermined by generating a random number between 0 and 2π using `Math.random()`, and then adjusting this value based on the number of options and the wheel's current rotation.

The tool uses React hooks such as `useState` and `useCallback` to manage its state and optimize performance. The `useState` hook is used to store the list of options, the current rotation of the wheel, and other state variables, while `useCallback` is used to memoize functions that depend on these state variables. This ensures that the tool's UI updates efficiently and accurately reflect the current state of the spin.

The animation's smoothness and performance are also optimized using the `requestAnimationFrame` API, which schedules the next frame of the animation at the optimal time for the browser. This allows the tool to take advantage of the browser's rendering pipeline and ensure a seamless user experience. The use of React and its ecosystem of libraries and tools enables the development of complex, interactive UI components like this spinning wheel, with a high degree of customization and control.

The `useEffect` hook is used to handle the cleanup of the animation when the component is unmounted, canceling any pending animation frames using `cancelAnimationFrame`. This ensures that the tool does not continue to consume system resources after it is no longer visible or in use. By combining these technologies and techniques, the tool provides a fast, efficient, and engaging way to make random decisions, with a unique and entertaining user experience.
