Issue Description

Going through the D3 challanges in beta, there are multiple ones that have always show the error "Identifier 'dataset' has already been declared." It appears to be a bug because the solution works if the const dataset line is commented out.

This happened on chrome. I checked and can't reproduce this error in Firefox quantum.
