Introduction to FormilyJS

FormilyJS is a high-performance form library that offers a comprehensive solution for managing forms in web applications. It is designed to solve complex form scenarios with ease, providing a data-driven approach to form creation, validation, and management. The core design purpose of Formily is to abstract form logic into a model that can be manipulated through JSON schema, making it easier to handle form state, validations, dynamic form structures, and complex form interactions. An example scenario illustrating its design purpose could involve dynamically generating a form based on user input, where fields, validations, and layout can change on-the-fly based on the data provided by the user.
