Functional Principle

LemonadeJS uses a reactive layer to synchronize changes between component properties and HTML elements. Key features include:

  • Two-way Data Binding: Synchronizes component properties with HTML element values.
  • Sugar: A pub/sub system for global state management and action dispatching.
  • Components: Reusable functionalities like data grids, modals, and calendars.
