Firebase validate a zip code

I tried the following regular expression

newData.val().matches(/(^\d{5}$)|(^\d{5}-\d{4}$)/)

I get an error that the escape character \d isn't recognized. I removed and cleared the errors but I still get a permission denied error.

You must use double slashes \\.

It will look like 

newData.val().matches(/(^\\d{5}$)|(^\\d{5}-\\d{4}$)/)

Take some time observing some of the examples that you can find on the documentation.
