Why Learn Regular Expressions?
Regular expressions, or regex for short, are one of the most powerful and applicable techniques in programming. We can use regular expressions to search for and find patterns in strings. They can be used in nearly every language, and they allow us to validate user input, perform search tasks, and even test code. Learn the rules of regular expressions so that you can apply them in any language of your choosing.
