JavaScript Regular Expressions

Character sets

In the following table, you can find the patterns for character sets, which tell the Regex to match only one character out of several characters.

Pattern	Description	Example
[xyz]	This matches any one character enclosed in the character set. You can use a hyphen to denote the range. For example, /[a-z]/ matches any letter in the alphabet and matches /[0-9]/ to any single digit.	/[ao]/ matches "a" in "bar"
[^xyz]	This matches any one character, which is not enclosed in the character set.	/[^ao]/ matches "b" in "bar"
