Installed VSCode plugin but still not able to catch deno syntax

Following the tutorial in the docs:

const res = await fetch("https://jsonplaceholder.typicode.com/todos/1");
const body = new Uint8Array(await res.arrayBuffer());
await Deno.stdout.write(body);

I still get underline on the await:

'await' expressions are only allowed at the top level of a file when that file is a module, but this file has no imports or exports. Consider adding an empty 'export {}' to make this file a module.ts(1375)

And underline on the Deno

Cannot find name 'Deno'.ts(2304)

while if I run the file with deno, it obv runs. But vscode underlines are very irritating as well as it is not giving any type suggestions for Deno object.

I installed the plugin Deno 1.32.0 by justjavac. I tried doing [command]+[p] and > Enable Deno, which says deno is already enabled.

I tried to find any similar issue but seems it’s not there while my issue is very basic regarding installation. I went through Readme but not able to solve the problem. Can you please help me what more I need to do to get it working?

I have this same issue in VS Code. I can see ‘Deno 1.0.2’ on the status bar, and other Deno syntax (such as import, await) seems to work (VS Code doesn’t report problems on them, only on the Deno name so far).

I got the same phenomenal in which Deno code suggestion and autocompletion did not work after installing denoland’s vscode_deno. After trying around I found the following steps help VS Code understands Deno - though this isn’t a configuration recommended by the plugin’s official documentation

• Create a directory named .vscode and then create a settings.json file inside that directory. Put the following JSON config in that file

  your-project-workspace/.vscode/settings.json

  {
    "deno.enable": true,
  }
  

• Open VS Code Settings File > Preferences > Settings (or Ctr + , on Windows / Cmd + , on macOS). Search deno, then select Extensions > Deno fron the search result filter.

• Check the Controls whether Deno is enabled or not to enable Deno like the above image capture.

• Restart VS Code, and hopefully Deno suggestion and autocompletion will work
