[beta] const breaks following challenges

See original GitHub issue

Challenge work-with-dynamic-data-in-d3 has an issue. User Agent is: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36. Please describe how to reproduce this issue, and include links to screenshots if possible.

The test case will not pass with the information below. However this same code does work in the next challenge “Add Inline Styling to Elements”.

    
    
<body>
<script>
  const dataset = [12, 31, 22, 17, 25, 18, 29, 14, 9];
  
  d3.select("body").selectAll("h2")
    .data(dataset)
    .enter()
    .append("h2")
    .text((d) => (d + " USD"));

    
    // Add your code above this line
</script>
</body>

    ```

I also had a problem with this exercise, with it throwing an error: Uncaught SyntaxError: Identifier ‘dataset’ has already been declared

When I removed the line const dataset = [12, 31, 22, 17, 25, 18, 29, 14, 9]; from the exercise it worked (the same is true for all the following exercises). I don’t know if the variable dataset is somehow being carried over from an earlier exercise.

Looks like Quincy opened another issue and assigned Berkeley to it (#12762), so I’ll close this in favour of that. Thanks for reporting everybody!
