Regular expressions (regex) are patterns used to match character combinations in strings, offering a powerful way to search and manipulate text that can replace dozens of lines of code. While the syntax can seem complex, understanding core components like character classes (e.g., [0-9] for digits, \w for word characters), quantifiers (e.g., + for one or more, * for zero or more), and anchors (e.g., ^ for start, $ for end) allows for effective pattern matching.
