new Event('myEvent') does not compile in typescript

https://developer.mozilla.org/en-US/docs/Web/Guide/Events/Creating_and_triggering_events

I am trying to create a custom event in typescript like above example:

var ev: Event = new Event('myEvent');

Sadly, in lib.d.ts, new for Event is parameterless:

declare var Event: {
    prototype: Event;
    new(): Event; // NO PARAMETERS!
    CAPTURING_PHASE: number;
    AT_TARGET: number;
    BUBBLING_PHASE: number;
}

Thus the constructor with a string parameter (event name) does not compile.

Any suggestions?

Most possibly you might be having an older version of typescript installed with its specific library files. The definition of Event is this way.

declare var Event: {
    prototype: Event;
    new(type: string, eventInitDict?: EventInit): Event;
    AT_TARGET: number;
    BUBBLING_PHASE: number;
    CAPTURING_PHASE: number;
}

I am not quite sure, but i believe typescript variables are not partials unlike interfaces. You could upgrade TS version, update lib.d.ts manually to edit the type or create a new type and use it.
