A regex, which is short for regular expression, is a sequence of characters that defines a specific search pattern. When included in code or search algorithms, regular expressions can be used to find certain patterns of characters within a string, or to find and replace a character or sequence of characters within a string. They are also frequently used to validate input.
I will be teaching you how to make a regex for an email validation and describing which parts of the regex describe what.
/^([a-z0-9_\.-]+)@([\da-z\.-]+)\.([a-z\.]{2,6})$/
