TypeScript ignores any unsupported JSDoc tags. To learn more, see our tips on writing great answers.

And its more verbose property definitions result in much richer IntelliSense: And here you see the IntelliSense we get from this: We could have gone with a simpler approach, which would work for types but would provide less useful IntelliSense: Although this is type correct, the resulting IntelliSense is very minimal: When it comes to how you define your types, it’s best to be more verbose as shown in the previous example of object types because it will result in richer IntelliSense. all other cases should return undefined. This is going to be much worse. Normally JSDoc templates would create an entire new page to display information about each level of a nested namespace hierarchy. When making a VM, why would I want to not pass it all my cpu cores? The actions interface manages a collection of actions.action objects. And the web is a hundred thousand times wilder than the Wild West. In Visual Studio Code, JSDoc comments will enable code completion, showing symbol definitions, symbol renaming across files, flaging of typos and unused variables, incorrect types, code completion, etc. operator, SyntaxError: missing } after function body, SyntaxError: missing } after property list, SyntaxError: redeclaration of formal parameter "x".
