No, you do NOT.

document.getElemtById(

should be

document.getElementById(

Same objection, you do not.

> return always the some object

Do you mean "the same object"?
If so, ofcourse,
if you request a pointer to a node twice
you get the same node twice.

> can someone explain me how that work

Why are you asking?
What do you want to accomplish?
This is not schoolwork, or is it?

It's the same as saying 1 === 1.

That might be true in a steady state.

However, things could have changed between the assignment of e
and the subsequent comparison in a way that the id has moved
[was signed] to another node.

> saying 1 === 1

That English has "one and another one" goes without saying.

Ah well, let's stipulate you are right, Sam.
