Cypress.$
Cypress automatically includes jQuery and exposes it as
Cypress.$.
Calling Cypress.$('button') will automatically query for elements in your
remote window. In other words, Cypress automatically sets the document to be
whatever you've currently navigated to via cy.visit().
This is a great way to synchronously query for elements when debugging from Developer Tools.

Notes
Cypress.$ vs. cy.$$
You can also query DOM elements with cy.$$. But Cypress.$ and cy.$$ are
different.
Cypress.$ refers to the jQuery function itself. You can do anything with
Cypress.$ if you can do it with the jQuery function. So, both of the
examples below work.
Cypress.$.each([1, 2, 3], (index, value) => {
expect(index).to.eq(value)
}) // works
$.each([1, 2, 3], (index, value) => {
expect(index).to.eq(value)
}) // also works
But cy.$$ is a wrapper of the jQuery.fn.init function. In other words, you
can only query DOM elements with cy.$$. Because of that, the jQuery utility
functions like jQuery.each, jQuery.grep don't work with cy.$$.
cy.$$.each([1, 2, 3], (index, value) => {
expect(index).to.eq(value)
}) // fails
