<!-- 🚨 STOP 🚨 𝗦𝗧𝗢𝗣 🚨 𝑺𝑻𝑶𝑷 🚨 Half of all issues filed here are duplicates, answered in the FAQ, or not appropriate for the bug tracker. Please read the FAQ first, especially the "Common Feature Requests" section. --> From https://github.com/Microsoft/vscode/issues/44824 ## Search Terms - quick fix / code action - jsdoc / jsdocs ## Suggestion Introduce a new refactoring that introduces a property into a jsdoc type. For example, for the js: ```js //@ts-check /** * @param {{ }} arg */ function doStuff(arg) { console.log(arg.noSuch); } ``` A quick fix on `noSuch` would add this property to the type of `arg`: ```js //@ts-check /** * @param {{noSuch: object }} arg */ function doStuff(arg) { console.log(arg.noSuch); } ``` A similar refactoring already exists for typescript: ```ts interface IFoo { a: number } function doStuff(arg: IFoo) { console.log(arg.noSuch); } ```  ## Use Cases Improve experience using ts-check, especially if using complex types ## Other cases to consider **typedef** ```ts //@ts-check /** * @typedef {{ a: number}} IFoo */ /** * * @param {IFoo} arg */ function doStuff(arg) { console.log(arg.noSuch); } ``` **Augments** ```ts /** * @augments {Component<{}>} */ class Binek extends Component { render() { console.log(this.props.noSuch) } } ```
