Understanding a skeleton of jQuery plugin
- by TK
At a website, I found the following code to make a jQuery plugin:
(function($){
// Our code here...
})(jQuery);
I don't understand how the code above works. What I understand is that the code executes immediately because the very last () in function(){}(). So the entire code says that is an anonymous function that is run immediately.
But I don't understand why the wrapping needs to pass jQuery and that inside it needs $ to be passed.
From my understanding, $ is an alias to jQuery, meaning practically the same. What is the meaning of $ and jQuery here? How does the overall code work as a jQuery plugin?
