Learn Webgpu - 10 Code Examples & CST Typing Practice Test
WebGPU is a modern, low-level graphics and compute API for the web that provides high-performance access to GPU hardware. It is the successor to WebGL, offering better performance, compute shaders, modern GPU features, and a more efficient programming model inspired by Vulkan, Metal, and Direct3D 12.

Explain
WebGPU exposes modern GPU capabilities to web applications for graphics rendering and compute workloads.
It is designed as a successor to WebGL with focus on compute shaders and low-overhead rendering pipelines.
The API is modeled closely after Vulkan/Metal/DX12 for explicit GPU control.
Supports GPU compute workloads beyond graphics (ML inference, parallel simulation, physics).
Runs in browsers without plugins through a secure, sandboxed GPU abstraction layer.
