Fabric.js vs react-three-fiber: What are the differences?

# Introduction
Key differences between Fabric.js and react-three-fiber are highlighted below:

1. **Primary Purpose**: Fabric.js is primarily used for 2D graphics rendering and manipulation, while react-three-fiber is designed for 3D graphics and animations.
2. **Rendering Technique**: Fabric.js utilizes the HTML5 canvas element for rendering 2D graphics, whereas react-three-fiber leverages WebGL under the hood for rendering 3D scenes.
3. **Component Structure**: react-three-fiber follows a component-based structure similar to React, making it easier for developers familiar with React to work with 3D graphics. Fabric.js does not have a similar component-based structure.
4. **Scene Management**: react-three-fiber provides a built-in scene manager to handle multiple 3D objects and animations more efficiently, whereas Fabric.js requires manual management of objects and animations in the canvas.
5. **Performance Optimization**: react-three-fiber is optimized for performance when dealing with complex 3D scenes and animations, thanks to its use of WebGL and advanced rendering techniques. Fabric.js may face performance limitations when handling complex 2D graphics operations.
6. **Community Support**: react-three-fiber benefits from the React community's support and a growing ecosystem of third-party libraries, while Fabric.js has been around longer and has a well-established community but may not have as many resources specifically tailored for 3D graphics.

In Summary, Fabric.js is focused on 2D graphics with HTML5 canvas rendering, while react-three-fiber is designed for 3D graphics leveraging WebGL and React-like component structure.
