    Interface Evented

    An interface allows to register listeners for objects that emit events. If you have a custom class that emits events, you may want to consider using Evented with EventedSupport.

    interface Evented {
        on(
            event: string,
            callback: (...args: any[]) => void,
            context?: any,
        ): Handle;
    }
