Working on fixing up & adding some tests to JS, have some questions for you.

1. There is no current requirement for unique hashtags - for example, "#hey #hey" should return ["hey", "hey"], correct?
2. Must every character in a hashtag be alphabetic? Currently it's unclear if, say, "#abc1" would count as valid
3. If the hashtag comes immediately before punctuation ("hey, let's meet up in #london, sound good?"), does that invalidate the hashtag entirely?

The test only tests the first item of the output. Which means, you can just match the first hashtag (if there's any) and pass all the tests.

• Ruby 3.0 should be enabled (Refer this & this for more detail)

Needs random tests

Expected: [], instead got: ["wha"]
I'm at a loss as to how to pass this test without knowing the input...

Expected: 0, instead got: 1
10 Passed
1 Failed

I wonder, what is for '0', as it is expected by the 11th test?
