How to call common js code from component js file?

Hi everybody!

I have a location component by path:

/ui.apps/src/main/content/jcr_root/apps/test/components/global/header/location. 

Under component directory I have a clientlibs folder with following properties and structure:

[cq:ClientLibraryFolder] - jcr:primaryType
     - categories="[test.location]"
     + js.txt (nt:file)
     + js (nt:folder)
     + validation.js (nt:file)

Here is the content of the validation.js file:

(function($) {
    console.log('test');
    console.log(location.add(5, 5));
})(jQuery, location);

And I have a file called location.js (just an example) under :

/ui.apps/src/main/content/jcr_root/etc/clientlibs/test/common

directory:

[cq:ClientLibraryFolder] - jcr:primaryType
     - categories="[test.common]"
     - embed="[test.global, test.location]"
     - dependencies="[cq.shared]"
     + css.txt (nt:file)
     + js.txt (nt:file)
     + css (nt:folder)
     + js (nt:folder)
      + location.js (nt:file)
      + a bunch of js files

Example of the content of location.js file:

var location = (function ($) {
     function init() {
        // some code...
     }
     function add(a, b) {
        console.log('a=' + a);
        console.log('b=' + b);
        return a + b;
     }
     return {
         add:add
     };
})(jQuery);
location.init();

So when I open the page and check browser console I see an error like this:

test
Uncaught TypeError: Cannot read property 'add' of undefined
    at common.dd1dbfad04c7d50b4c3973155ce3fa63.js:7081
    at common.dd1dbfad04c7d50b4c3973155ce3fa63.js:7082

It's happening because code from validation.js is higher than code from location.js in the compiled common.js file.

AEM version is 6.3.2.2.

So my question:

Is it possible to call some function from js file with common code inside js file related to component? If yes, how I can achieve that?

Thanks in advance!
