What are best practices for working with basic regex syntax?

Regular expressions (regex) are a powerful tool in Perl for searching, matching, and manipulating strings. Here are some best practices for working with basic regex syntax in Perl:

• Understand Character Classes: Use square brackets to define a class of characters that you want to match.
• Use Anchors: Use '^' to match the start of a string and '$' to match the end of a string.
• Be Specific: Avoid overly broad patterns to improve performance and readability.
• Utilize Non-capturing Groups: Use '(?:...)' for grouping without capturing for better performance.
• Test Regular Expressions: Use tools or online regex testers to ensure your regex behaves as expected.
• Comment Complex Regexes: Use the 'x' modifier to allow for comments and whitespace within regex for clarity.
• Precompile Regexes: Use variables to store precompiled regex patterns when reusing them.
• Beware of Greediness: Use qualifiers wisely; prefer non-greedy matching by appending '?' to quantifiers when needed.
