Deno WebGPU Activation: Command Line and Configuration Methods

Deno users have two convenient methods to enable WebGPU:

• Command-Line Flag: Run your script with the --unstable-webgpu flag. This is a quick and easy method for testing and development.
• deno.json Configuration: Add the following to your deno.json file:

"unstable": [
  "webgpu"
]

Configuring deno.json provides a persistent solution, automatically enabling WebGPU for all scripts within the project. Ensure you are using Deno version 1.39 or newer.

Chrome on Android and Desktop: Ensuring WebGPU is Active

WebGPU should function by default in the latest Chrome versions on both Android and desktop. If you encounter issues, consult the official Chrome developer documentation on troubleshooting for specific experimental flags that might need enabling. Keeping Chrome updated is crucial for optimal WebGPU support.
