temp-zadfghcabp.typescript: Do you intend to select a piece of code snippet to run?

[axefrog]

I just made an untitled file (unsaved in a tab), set the language to typescript, pasted some code in, then pressed CTRL+SHIFT+N to run it. Do I need to select it as well?

[formulahendry]

Got it. So did you try to run the same code (with ts-node) in the terminal?

[philmueller]

@axefrog: The reason is that the automatically generated temporary file for your unsaved code (tempCodeRunnerFile.typescript) doesn't end with ".ts", so ts-node seems to interpret it as JavaScript instead of TypeScript. As a workaround, you can save the file with ".ts" ending or add the following to your user settings:

"code-runner.languageIdToFileExtensionMap": {
  "typescript": ".ts"
}

@formulahendry: I've created a corresponding pull request to apply the correct file ending to the default configuration (#166).

That's cool. Thanks @philmueller !
