what does $(dollor sign) parameter means?

[#1]

when making a extension, on js file, we put

define(["qllik", "~~~.html",...]),

function(qlik, templates, $){

}

something like this.

I wonder what does that dollor sign means..

Is there anybody could answer this question??

well in your example ... means $.

When you define your module you can import dependencies and then those dependencies are aliased in the function call. So

define(['mycoolmodulealiasedto$', otherdepaliasedtoQ], function($,Q) {})

Now normally though people would reference a jquery dependency as $ since that is fairly common in the web developer world.
