chapter-3's Issues

Need to limit search results for listing-3.12 to avoid "400 Error"

If you run listing-3.12.js as is you'll get:

{ StatusCodeError: 400 - "Error 400: Bad Request\n\n20160 matching events exceeds search limit of 20000. Modify the search to match fewer events.\n\nUsage details are available from https://earthquake.usgs.gov/fdsnws/event/1\n\nRequest:\n/fdsnws/event/1/query.csv?starttime=2017-01-01&endtime=2017-03-02\n\nRequest Submitted:\n2019-01-23T22:45:30+00:00\n\nService version:\n1.7.0"

This is because the API has a defined limit on the number of items that can be returned (20k). If we limit the number of items in the request it will avoid the issue, and this can be done by changing the URL on line 4 to:

const url = "https://earthquake.usgs.gov/fdsnws/event/1/query.csv?starttime=2017-01-01&endtime=2017-03-02&limit=20000";

I could submit a PR if that would help but it's just a one line fix.

Hope this helps.

Need to remove the semicolon on line 4

listing-2.js not included in repo

Is cited in the book, however.

https://livebook.manning.com/#!/book/data-wrangling-with-javascript/chapter-3/v-2/68

I see now that many of the listings are included. Perhaps intentional.
