Regular expressions can be difficult learn and remember. That's why I created these regular expression laptop stickers. With these stickers, you'll be reminded of each regular expression every time you look at your laptop, and over time, you'll memorize them automatically. It's also a great conversation starter for other people who notice your awesome stickers!

Product Features
Each package of regular expression stickers comes with the 8 unique stickers shown in the image above:
- /https?/ - A regular expression that will match the string 'http' with an optional 's' at the end.
- /null|nil|None/ - A regular expression that will match any of the strings 'null', 'nil' or 'None'.
- /-?\d+(\.\d+)?/ - A regular expression that will match any positive or negative integer or decimal number.
- /^.+@.+$/ - A very crude regular expression to match an 'email address'. In reality, it just matches a '@' character that appears between two sets of one or more non-newline characters (this will include a lot of invalid email addresses).
- /[A-Za-z_\-]+/ - A common regular expression that might be used to match an 'identifier' that consists of any upper-case or lower-case letter of the alphabet, an underscore, or a '-' character, one or more times.
- /[A-Z]{3,5}/ - A regular expression that will match a string that consists of 3 to 5 upper-case letter of the alphabet.
- /#[A-Fa-f0-9]{6}/ - A regular expression that will match 6-digit hex-encoded HTML color codes like '#00FF00', or '#FEFEFE'.
- /[\n\r\t ]/ - A regular expression that will match a single character that is either a newline, a carriage return, a tab, or a normal space.
