Hello world!
Often in jsquery i see syntaxis $("#_some_id") - can u explain me what is this means? and how i can use it without jsquery?
Thanks!

A crude translation is

document.getElementById("_some_id")

jQuery actual does not return the element but an object refering to the element.

if you replace # by other, you can do all getElementsBy... and much more.
