Description
When the library code executes, if it encounters an `jQuery` object which has not been fully initailized or in invalid. JSBarcode throws a error TypeError: Cannot set property 'JSBarcode' of undefined.
Steps to reproduce
1) Inject a broken jQuery into the HTML file ( jQuery = {}; ).
2) Try to render the page with JSBarcode.
The broken jQuery maybe cause of incomplete code injection (due to slow network) of any plugin added as extension.
