If you come from a web development background, please note that, at the time of writing this book, there is no form component, and I don't see it coming. There are also limitations to refs and what you can do with them. For instance, you cannot ask a ref to a TextInput for its current value. Please follow the following two subsections for more details. You can also use custom libraries, but I will not discuss such solutions here as these tend to change often.
