Groups & Backreferences - RegEx Beginner Tutorial
Groups in regular expressions come in two forms - capturing groups and non-capturing groups. Capturing groups work together with backreferences to reference saved matches.
Regex groups and backreferences in C#, JavaScript, Java, or Python work similarly. You can also turn them into named capturing groups and named backreferences for easier reading.
Disjunctions are often used with groups to match either one thing or the other (alternatives) using a pipe symbol. This regex beginner tutorial shows how to use groups and how to use backreferences.
