Regular Expression Pitfalls, Optimization, and Performance Improvements
Regular expressions, if not written well may perform poorly. They may run slowly, and when they are executed frequently in some code, they may be the source of high CPU utilization. To avoid these problems, regular expressions have to be crafted carefully, understanding the possible pitfalls, and they also have to be tested thoroughly. We will be covering the following topics in this chapter:

- How to test your regex functionality and performance
- Optimization and performance enhancing tips
