✅ 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

TypeScript currently only supports auto-completion for JSDoc, not TSDoc. For example, there is no intelligent suggestion for @defaultValue.

📃 Motivating Example

If TSDoc is the recommended commenting standard for TypeScript, then it should natively support intelligent suggestions and syntax highlighting for TSDoc.

💻 Use Cases

Writing comments using TSDoc syntax in VSCode.

首先调查 TypeScript 当前如何提供 JSDoc 自动补全，以及 VSCode 如何使用这些语言服务结果。将该行为与 @defaultValue 等 TSDoc 标签进行比较，并确定预期的语法高亮和补全行为；完成的标准是 TSDoc 注释能够获得智能建议，同时不改变生成的 JavaScript。
