Typescript return type for adhoc return value

Question

Suppose that I have the following function in Typescript 2.0:

doSomething(): any {

    const apple: Apple = ...
    const pears: Pear[] = ...

    return {
        apple: apple,
        pears: pears
    }
}

I know that my function will always return an object that has an apple property of type Apple and a pear property of type Pear[].

I don't especially want to create a new class to model this. Is there anyway to change my return type from any to something more meaningful?

Answer 1

You can use an inline interface:

doSomething(): {apple: Apple, pears: Pear[]} {

    const apple: Apple = ...
    const pears: Pear[] = ...

    return {
        apple: apple,
        pears: pears
    }
}
