Consider this bit of code:
// declare a function that accepts an argument
var myFn = function(myParam) {
// inside here I can use myParam freely
};
// call the function and pass an argument
myFn(3);
Now, change what you call the parameter name and what you pass to the
function
var myFn = function($) {
// inside here I can use $ freely
};
// call the function and pass jQuery as the argument
myFn(jQuery);
Now do it all in one step, as an anonymous function:
(function($) {
// inside here I can use myParam freely
})(jQuery);
