Angular2 typescript syntax

I understand that we can specify the type of a variable in TypeScript using a colon. Here, _emitters is a variable which has a type which is specified after the colon sign.

However I am struggling to understand what type is assigned to _emitters in the below code. 

private static _emitters: { [ID: string]: EventEmitter<any> } = {};

It is probably very basic, but unfortunately I am unable to understand it.

It's an object that has keys of type string. Each key of the object holds an EventEmitter.

The example is missing the type of emitted value, eg. 

EventEmitter<string>
