Could not complete module assignment, because the Grading Software does not pass the file. No it is not a technical problem with the file. Course cannot be completed without use of third-party IDE environment. This was not explained in the Course Description page, the page even suggests that the course can be completed without additional software, but it is not true. Contacted Support many times. Received only disconcerted ambivalence from Coursera Support. Disappointing waste of time and effort, discouraging the experience of learning online. Systematic failure of Coursera, both in regard to maintaining reasonable expectations of course content, as well as followup through Coursera Support seeking resolution. Very disappointed.
This is the second course in the four‑course Computational Thinking with JavaScript Specialization. Building on the foundations from Course 1, the emphasis here is on modelling aspects of the real world using computational representations, particularly data.
