AS A web development student
I WANT a tutorial explaining a specific regex
SO THAT I can understand the search pattern the regex definesA 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.
For example, the following regular expression can be used to verify that user input is a valid email address:
/^([a-z0-9_\.-]+)@([\da-z\.-]+)\.([a-z\.]{2,6})$/
Each component of this regex has a unique responsibility to make sure that a user enters an email address that begins with an unspecified number of characters preceding the @ symbol, followed by a domain.
