just a quick question

I am very new to javascript i was looking over some code and found something i didn't understand

 

function scroll(d){
if(d == "up"){
	$("#log").scrollTo('-=100px',800);
} else {
	$("#log").scrollTo('+=100px',800);
}

 

my question is why is there a $ within the code as i know its not how they do variables is it too do with html or css elements?

 

thank you for reading and any help you can give

You can name variables $ within Javascript.

 

Given that jQuery uses $ to store the jQuery object and that there is a plugin for jQuery called scrollTo I would say the code you have there is jQuery.
