    I have 10 years IT experience and so far I never bother learning about regex, yet the irony is i almost use it on day to day basis. I simply Google and copy-paste the regex.
    Your video helped me understand the basic concept very well!

      true, there are a lot of templates for regex. Sometimes happen you need to write your own in a specific situation like validation but it's simple case.

    In the second task You have a little bug. The task "only one digit allowed in between" indicates that the last [a-z] should have not * (0 or more) but + (1ore more). Otherwise the digit will not be between the letters. Everything else is just beautifull and simply shown

      * is for the number of repetitions not for the number of characters for instance [a-z] * simply means it should atleast have 1 character between a to z and * there means 0 and more repetitions are possible do correct me if I'm wrong

    @6:43 should it not be + instead of * because the rule says it DOES Contain lower case, so it should happen one time or more times(the rule for +)? I felt it should be both pluses? Because there has to be a lower and an uppercase (can't be zero, so no *) and there has to be a number in between. So both pluses?
