✅ Viability Checklist

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• This isn't a request to add a new utility type: https://github.com/microsoft/TypeScript/wiki/No-New-Utility-Types
• This feature would agree with the rest of our Design Goals: https://github.com/Microsoft/TypeScript/wiki/TypeScript-Design-Goals

⭐ Suggestion

Types that are explicitly set to any are sometimes hard to distinguish from actually typed variables in the editor. You might be adopting types while still having a lot of any around and then it would be helpful to call any out more explicitly in the editor.

I am now using the extension https://marketplace.visualstudio.com/items?itemName=danvk.any-xray which does this:

💻 Use Cases

1. What do you want to use this for?

Seeing explicit any types easily so that I can work on adding types.

3. What shortcomings exist with current approaches?

I can disable explicit any by producing errors but that is very aggressive.

5. What workarounds are you using in the meantime?

Hovering over the type.

この issue では、明示的に宣言された any 型を示すエディター表示について説明し、参照として any-xray 拡張機能を挙げています。まず、TypeScript がエディターに型情報をどのように公開しているかをたどり、関連するエディターまたは language-service のテストを確認します。意図した表示がランタイム出力を変更せずに実装され、テストでカバーされていれば完了です。
