Just a quick question to help clear up some confusion.
Joel mentions the match() method but seems to use the test() method in its place. Do these 2 words means the same method? Are they used interchangeably? :) thanks

The match() method retrieves the matches when matching a string against a regular expression.
Use .test if you want a faster boolean check. Use .match to retrieve all matches when using the g global flag.
Enjoy!

Treehouse Moderator 91,252 PointsI appreciate the response, thank you!. :-)
The question was more about why we don't see an example of match() in the video. Unless we did and I somehow missed it!
