Functional Components & Event Management
A. Functional components are simple JavaScript functions in React that return JSX (UI elements). They are the modern way to build React apps because they are cleaner and easier to manage than class components.
In this project, the entire Unit Converter app is built from a single functional component, UnitConverter. It handles the UI structure, state, and logic together, making the code easy to understand and maintain.
B. Event management in React refers to handling user actions such as clicks, keystrokes, and selections. It helps the application respond to user interactions with the interface.
In this project, event management is used when users switch tabs, select radio buttons, type values, or click the swap button. Each action triggers a state update, which keeps the UI fully interactive and responsive.
