If you know how to fix the issue, make a pull request instead.

• I tried using the @types/node package and had problems.
• I tried using the latest stable version of tsc. https://www.npmjs.com/package/typescript
• I have a question that is inappropriate for StackOverflow. (Please ask any appropriate questions there).
• Mention the authors (see Definitions by: in index.d.ts) so they can respond.

If you do not mention the authors the issue will be ignored.

I was wondering if at some point the definition of EventEmitter should be changed to be more generic eg.

    export class EventEmitter<
    T extends { [key: string]: any } = { [key: string]: any },
    > {
        static listenerCount(emitter: EventEmitter, event: string | symbol): number; // deprecated
        static defaultMaxListeners: number;

        addListener<K extends keyof T>(event: K, listener: (arg: T[K]) => void): this;
        ...

This would drastically improve type safety for consumers and simplify definitions.

Known issues:

• 2nd degree inheritance cannot easily
• symbol is not supported as a generic index type.
• multiple arguments are not possible to be implemented this way eg. ...args

All of these needs to be resolved either by manually declaring the signatures (as done right now) or via declaration merging (also done by some right now).
