Description

This issue was caused because of the use of latest ES6 feature assert, which is not supported by all the browsers at the moment especially non-chromium based browsers.

I replaced that implementation with the old widely accepted import statement, by making minimum changes required.

It is advised that futures coders don't implement the beta features in the code.
