Good reasons to use .matchAll()

1. It can be more elegant when using with capture groups. A capture group is simply the part of regular expression with ( ) that extracts a pattern.

2. It returns an iterator instead of array. Iterators on their own are useful.

3. An iterator can be converted to an array using spread operator (...)

4. It avoids regular expressions with /g flag... useful when an unknown regular expression is retrieved from database or outside source and used together with the archaic RegEx object.
