Full Stack JavaScript Techdegree Student 11,196 PointsMy solution for this practice
Here is my solution:
- Exclude "a" and whitespace, and match one or more alphanumeric characters:
[^a\s]\w+ - Match 5 numbers:
\d{5} - Match commas:
, - Exclude "<", ">", "/" and whitespace and match one or more alphanumeric characters:
[^<>\/\s]\w+
I hope this helps!

For 2 and 3, I think they were looking for a different answer, as the lesson was on excluding characters, so for number 2 I would have went with something like \d+[^\w]*$. For number 3 I might have gone with something like [^a-z]*, which seems unnecessary, since yours does pretty much the same thing, ultimately excludes everything except the comma.
It's not clear on number 4 if they also wanted you to exclude the slashes.

Full Stack JavaScript Techdegree Student 11,196 PointsHi Jason Larson!
Thank you for sharing your opinion!
For the first example, I think they meant us to exclude the exact "aaaaa" string, given that we are working with string made of only letters.
For 2 and 3 I went for the "easy way", because in the Teacher's Notes it states "Using what you've learned so far, create a regular expression..." so I used everything I learned in the course up to that point in time.
For number 4 you might be correct. We must exclude "/" because it says "Match only text characters...". I will edit the original post to avoid confusion for future readers.
