⭐ Suggestion

Currently the javascript.inlayHints.functionLikeReturnTypes.enabled setting in VS Code adds inlay hints to JS functions that do not have an explicit @return annotation:

// Shown here
function foo() /* : number */ { 
    return 1;
}

// But not here here
/** @return {number} */
function foo()  { 
    return 1;
}

This feels inconsistent, since I now have to look in different locations for the type information

I propose adding a new option that always enables these return types in JS files, even if there is an @return type annotation.

In the example above, this would result in the inlay hints showing on both functions:

function foo() /* : number */ { 
    return 1;
}

/** @return {number} */
function foo()  /* : number */ { 
    return 1;
}

This lets me read the code more like standard TypeScript

Comienza rastreando la configuración existente javascript.inlayHints.functionLikeReturnTypes.enabled y cómo se suprimen los tipos de retorno cuando hay una anotación @return. Define la interacción de la nueva opción con esa configuración y, después, verifica que tanto las funciones de JavaScript anotadas como las no anotadas muestren sugerencias insertadas del tipo de retorno cuando esté habilitada.
