Enhance explanations / checks around what is supported by the scrapper

[benoit74]

Currently, the README states that:

Currently this scraper only supports Javascript challenges.

However, it is a bit unclear what Javascript challenges are exactly.

Is it only courses under the javascript-algorithms-and-data-structures superBlock?

If yes, is there any reason not to include es6 in the sample commands?

And finally, regarding these sample commands, what is the logic around course order in the CSV? Is it based only on personal taste?

@rgaudin @mdp your help is more than welcomed 😃

It's based on the kind of course ; those JS course have this tester that has been implemented while other languages use videos for instance. I think you'll have to check to es6 and it's possible there are some compatible courses here and there.

As for the list in the README (CSV???) I believe that's the order from the folder listing. Not sure though

[benoit74]

How do I find what is the kind of a course? is it linked to the challengeType property?

The CSV = the Comma Separated Value (i.e. the --course parameter which is comma separated)
