02 One of several characters

2 / 16

Goal

Match both spellings: gray and grey.

Square brackets make a character class: [ae] matches exactly one character, which may be a or e. It's one slot with a choice, not two characters.

That's why graey fails: after gr, the class consumes one character, and the next must be y.

Try it

Catch both spellings, and nothing else.

Hint

/gr[ae]y/ — [ae] matches one character, either a or e.
