Description
Regular expressions can be extremely useful whenever you need to make the computer do something with text.
For example, when you need to check that what user typed is a real email, or automatically replace every uppercase letter F into a lowercase letter F.
But as useful as they are, regular expressions can be extremely confusing and intimidating for beginners.
In this podcast I’m going to explain regular expressions in a simple and accessible way, and help you start using them in your day-to-day work.
