Function Decorator

[CofeeWithRose]

Suggestion

support function no in class Decorator.
In react app, I hope to use decorator to define the route information of function components.

Use Cases

Page.tsx

@Reflect.metadata('Route', { path: '/home' })
export function Page(){
  return <div> Home Page </div>
}


console.log(Reflect.getMetadata('Route', Page).path ) //   "/home"

Examples

Checklist

My suggestion meets these guidelines:

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

Duplicate of #7318. And this would first require JavaScript to support function decorators.
