jquery - Error Using Foundation 6 Equalizer plugin -

i'm concatenating foundation 6's core.js, util.mediaquery.js, , equalizer.js files. in source code, source order jquery first, foundation.core.js, util.mediaquery.js, , plug-in file, per documentation. compile js ecmascript 2015, using babel per zurb's docs.

this error occurs util.mediaquery.js included:

uncaught typeerror: foundation.onimagesloaded not function(…) 

this error occurs without util.mediaquery.js included:

uncaught typeerror: cannot read property '_init' of undefined 

i'm not sure it's relevant include snippets these errors reference. according zurb's documentation equalizer: "the file foundation.equalizer.js must included in javascript use plugin, along foundation.core.js.".

and, true form, you'd need visit different page within docs read "if you're using plugins, know require foundation.core.js , foundation.util.mediaquery.js loaded first".

despite nebulous direction provided zurb's docs, 1 of 2 above scenarios should produce functioning plug-in rather error.

any insight why it's occurring appreciated.

i'm writing web application , only using the equalizer plugin. appears tabs container required dependency.
