How do I reference a jQuery selector using TypeScript and DefinitelyTyped?

Question

I'm creating a method in TypeScript that should receive a jQuery selector as a parameter and I want to make it strongly typed by using DefinitelyTyped. How should my method be like?

Example:

class Foo {
    constructor($el: jQuerySelector) {
    }
}

What should I replace jQuerySelector with?

Answer 1

e.g. $('div') in the DefinitelyTyped jquery.d.ts is named JQuery.
