Validate function documentation

[benlieb]

Great library, much appreciated!

That said, I can't find any docs on the validate function except:

It doesn't say what to return to influence the error creation etc.

I asked copilot and it suggested:

          rules={{
            required: 'required',
            validate: (value) => {
              if (value.split(' ').length > 1) {
                return 'no spaces allowed'
              }
              return true;
            }
          }}

But it seems the return true may not be necessary? This seems to work fine?

          rules={{
            required: 'required',
            validate: (value) => {
              if (value.split(' ').length > 1)
                return 'no spaces allowed'
            }
          }}
