Regular Expression Character Classes: Negation & Character Ranges

This video continues the discussion of how character classes work on regular expressions: There are two remaining characters that must be escaped in a character class. These are the dash character and the caret character. The dash character is used to describe a character range, which is a short way to specify a list of consecutive characters. The caret character is used to describe a negated character class. A negated character class simply means to define the set of character that we *don't* want to match, rather than defining the set of character that we do want to match.Interactive versions of the animations in the video can be found here:

Another great video. While I understood character classes in use, learning how they work opens up a lot more possibilities. Thank you.
