Hi there!
There is a lot of information about regular expressions on the internet and several great resources like Regex101. Still, sometimes it is always hard for me to choose among all the wide variety of options available. Besides that, since my team develops in multiple languages, it's hard to remember the differences between the APIs and syntax in each of the language. That's why at some point we started to collect the list of most commonly used regular expressions and the code examples of how to use them. Since the list became pretty large we decided to make it public and share it with the dev community. Hope you find it useful and let me know if there are some additional regular expressions you want to see there.
