What are you trying to achieve or the steps to reproduce?

I'm new the the library and was just trying the examples listed in the documentation. Everything I tried worked as expected, except the lazy example for recursive schemas. See example from docs below:

const Person = Joi.object({
  firstName: Joi.string().required(),
  lastName: Joi.string().required(),
  children: Joi.array().items(Joi.lazy(() => Person).description('Person schema'))
});

What was the result you got?

children: Joi.array().items(Joi.lazy(() => Person).description('Person schema'))
                                  ^
TypeError: Joi.lazy is not a function

What result did you expect?

That it worked. All you other examples from the documentation works as is. I think this is a bug, otherwise the documentation might benefit from an extra line explaining usage.

Thank you

Close - I'm on the wrong version of the docs. Sorry
