Is there a way to apply a decorator to a function that has been returned?

Can the following be accomplished?

bar () {
    @custom
    yield () => {
    }
}

Answer №1

It's not possible to adorn an expression with decorations.

However, you can achieve the desired result by enveloping the returned function.

bar () {
    return wrapper(() => {
    });
}
