Front End Web Development Techdegree Student 10,263 PointsConfused about /^[^@]+@[^@.]+\.[a-z]+$/i.test(email);
What does [^@] mean? Does it mean "any character" in JavaScript? Also, a simpler way to do this would be
^.*@.*\.[a-z]+$

231,236 PointsIn a regular expression, "[^@]
" is what's known as a "character class" and it means "any character other than an @ (at-sign)".
The brackets indicate a character class (code that will represent a single character), and when the first thing in it is a caret (^), it means "anything but" whatever follows. The @ has no special meaning and just represents itself.
So you don't want to replace it with the dot wildcard, because that would also match @.
