Regular Expressions test() - match()? Are these used interchangeably?

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 test() method executes a search for a match between a regular expression and a specified string. Returns true or false.

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.

I 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!
