The regex for a phone number is 10 digits and allows "-" (Javascript)
so I got the score and one of the regex is a phone number which has 10 numbers but also allows a dash "-". However, it can only contain two dashes and start with a 0. for example. 0x-xxxx-xxxx, where x can be any digit between 0-9.
So, so far I have come across the following regular expressions:
^[0-0][0-9-]{1,11}$
^[0-0][0-9-]{11}$
In the first it works but allows any length if I put 5 numbers it goes through until the first is 0. In the second I can put 2 hyphens following one after the other, or just fill it with a dash and it goes through.
Thanks for helping the guys!

Match each of the three parts separated by strokes, for example:
^0\d-\d{4}-\d{4}$
This corresponds to 0x-xxxx-xxxx. Demo: https://regex101.com/r/nW7wL5/1
If you also want to match a number without a dash, use
^0\d-?\d{4}-?\d{4}$

\d
is the same as [0-9]
but shorter.
