react-select: doesn't compile since OptionType is a ReadonlyArray

[paillave]

Since the commit bd1dc27 such a code doesn't compile anymore (the issue is at console.log([value.id])):

import { ValueType, ActionMeta } from "react-select/lib/types";

interface IOptionType {
    id: number;
    name: string;
};

function mappedOnChange(value: ValueType<IOptionType>) {
    if (value) {
        if (value instanceof Array) {
            console.log(value.map(i => i.id));
        }
        else {
            console.log([value.id]);
        }
    }
}

Actually, the issue is not here but in TypeScript it self.
here is the issue with the workaround mentioned at the end: microsoft/TypeScript#17002
