I have a script called "utils.js" that contains multiple functions that can be reused cross multiple files. So how can i convert this function in a way to work in multiple files when is called?

Example:

function myMultiscriptsGetter(pScript){
// do the same logic of $.getMultiScripts
//Note: this function will be in my "utils.js" file

}

Then in any other script i just need to include the "utils.js" and call the function, like this :

$.myMultiscriptsGetter(pScript).done(function() {
            // all scripts loaded !
        });

Note: I tried this but it doesn't work. I dont have a lot experience with jquery

What I have tried:

Currently, i have this function:

$.getMultiScripts = function(arr, path) {
            var _arr = $.map(arr, function(scr) {
                return $.getScript( (path||"") + scr );
            });

            _arr.push($.Deferred(function( deferred ){
                $( deferred.resolve );
            }));

            return $.when.apply($, _arr);
        }

Then, is called:

$.getMultiScripts(pScript).done(function() {
// all scripts loaded !
});
