### How to use the `using` declaration in your Worker

Because it has not yet landed in V8, the `using` keyword is not yet available directly in the Workers runtime. To use it in your code, you must use a prerelease version of the [Wrangler CLI](/workers/wrangler/) to run and deploy your Worker:

```sh
npx wrangler@using-keyword-experimental dev
```

This version of Wrangler will transpile `using` into direct calls to `Symbol.dispose()`, before running your code or deploying it to Cloudflare.
[Wrangler](/workers/wrangler/) v4+ supports the `using` keyword natively. If you are on an earlier version of Wrangler, you can alternatively call dispose of resources manually.

@GregBrimble Sorry I didn't realize you had auto-merge on. I think you have a typo here. Can you confirm my suggestion here and I'll make another PR to fix it?
