still remember my doomed encounters with regular expressions backwhen I tried to learn them. In fact, I took pride in not using regularexpressions. I always found a long workaround or a code snippet. Iprojected and blamed my own lack of expertise on the hard readability ofregular expressions. This process continued until I was ready to face thetruth: regular expressions are powerful, and they can save you a lot of timeand headache.Fast-forward a couple of years. People I worked with encountered thesame problems. Some knew regular expressions, and others hated them.Among the haters of regular expressions, it was quite common that theyactually liked the syntax and grammar of their first programming language.Some developers even took courses on formal languages.
