// @ts-check no longer seems to work for js files in implicit project

[mjbvz]

TypeScript Version: 2.6.1-insiders.20171019

Steps to Reproduce

1. Open an empty folder in VS Code

2. Open a blank js file.

   // @ts-check
   let b = 123;
   b = ''

Expected behavior:
With VS Code and TS 2.5.2 this is reported as an error.

            "code": 2322,
            "category": "error"
        }
    ]
}

Actual behavior:
No error with 2.6

We never receive the semanticDiag message in this case

@Andy-MS can you take a look.

This is working for me in an empty directory with a file a.js containing just the text you pasted.
I'm using typescript@2.6.1-insiders.20171019 like you said.
Is it possible that you have a jsconfig.json or tsconfig.json in an ancestor directory?

[mjbvz]

I don't think so but let me double check on that. Are you also using vscode insiders?

[mjbvz]

Ok, so you also need to have an untitled file open in the javascript mode to reproduce this. I missed this step when reporting it.

Steps to Reproduce

1. Open an empty folder in VS Code

2. Create a new untitled file using file -> new.

3. Set the language mode of the file to javascript

4. Now create a real js file on disk called index.js using the VS Code explorer

   // @ts-check
   let b = 123;
   b = ''

5. Notice no errors being reported

[mhegazy]

might be caused by #19228

I tried that too and I still see the error. Using vscode insiders, updated this morning. I removed all settings except "typescript.tsdk": "/home/andy/.nvm/versions/node/v8.6.0/lib/node_modules/typescript/lib".

There will be two tabs open when those steps are complete, right? One empty untitled file in JS mode and another for index.js.

[mjbvz]

Ok, with the above project setup can you try:

1. Have both the untitled and file on disk open in the editor
2. Open the untitled file
3. Reload the VS Code window
4. The untitled file should open again and still should be in js mode
5. Now switch back to the js file on disk

That is still working for me. Do you have any settings on besides typescript.tsdk and "typescript.tsserver.log": "verbose"? Could you double-check your globally installed typescript version?
