Textures are a fundamental concept in 2D graphics, especially when working with PixiJS. A texture is essentially an image or a section of an image that you can use to draw graphics on the screen. In game development, textures are used to represent characters, backgrounds, objects, and effects. By applying textures to sprites, you can bring your game visuals to life without manually drawing every pixel. Efficient management and loading of textures are crucial for performance and a smooth player experience.

Loading textures in PixiJS is an asynchronous process. This means that when you request a texture from a URL or file, the browser does not pause everything else while waiting for the image to download. Instead, it continues running your code and only notifies you when the texture is ready to use. This approach avoids freezing or slowing down your application, especially if you are loading large images or many assets at once.

As a best practice, always use the loader's completion events or callbacks to ensure you only create sprites or start your game logic after all necessary textures have finished loading. This helps prevent errors and ensures that your game visuals appear as intended.
