What you'll learn

  • Handle strings efficiently in your language
  • Define complex expressions using character classes, ranges and conditions
  • Control the behavior of regular expressions with flags

Description

Regular expressions (Regexp) are a powerful way to process strings, allowing you to find substrings (part of a string) in strings according to complex conditions. They are present in all high-level languages without exception and are often encountered in everyday work. However, you can only use the full power of regular expressions if you understand their language.
