What is Regex?
A regular expression (regex) can loosely be perceived as a programming language that is most commonly used to find/match patterns within text. A very basic and well-known example of regular expressions in use is any find, or find-and-replace, feature in a text editor.
Due to the steep learning curve regex can have, this application is designed to be a softer introduction to generating regular expressions. By utilizing the simple nature of Blockly, users can click and drag components of a regular expression and craft a string with little difficulty. Additionally these strings can be tested on the application with ease.
