Answer 2

This function behaves the same as $ (document) .ready (), because it should be used to transfer other $ () operations on your page, which depend on the readiness of the DOM. Although this function is technically connected to a circuit, it is actually not very convenient to use to bind to it.

$ is basically a way to call the jQuery class.

jQuery.doSomething();

$.doSomething();
