✅ Viability Checklist

My suggestion meets these guidelines:

  • [x] This wouldn't be a breaking change in existing TypeScript/JavaScript code
  • [x] This wouldn't change the runtime behavior of existing JavaScript code
  • [x] This could be implemented without emitting different JS based on the types of the expressions
  • [x] This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
  • [x] This feature would agree with the rest of TypeScript's Design Goals.

⭐ Suggestion

Use @throws to mark the corresponding error on the method in the .d.ts file in the lib directory

📃 Motivating Example

 * Converts a JavaScript Object Notation (JSON) string into an object.
 * @param text A valid JSON string.
 * @param reviver A function that transforms the results. This function is called for each member of the object.
+* @throws {SyntaxError} if the string to parse is not valid JSON. 
 * If a member contains nested objects, the nested objects are transformed before the parent object is.
 parse(text: string, reviver?: (this: any, key: string, value: any) => any): any;

💻 Use Cases

Something like typescript-eslint/no-floating-promises would be interesting. In this rule unhandled promises shows an error on vscode.
