    It has a not keyword it’s used for pattern matching.

    if (x is not null)

        Pattern matching is different.

          Yeah, I just said it since you used it with null. I used it a lot for enums

            The type matching is the most common thing I use it with. Combined with inline variables.

            if (x is string { Length: 5} s)
            {
                // do stuff with s
            }
            

            And switch expressions.

            As a side note inline variables are amazing haha
