React Fundamentals Wrap-Up

What is React:

React is a widely used JavaScript library for building user interfaces;
It empowers developers to create reusable UI components and efficiently manage state and data flow.

JSX (JavaScript XML):

JSX is a syntax extension for JavaScript, enabling the integration of HTML-like code within JavaScript;
It offers a concise and expressive way to define the structure and appearance of UI components.

Rendering Elements in React:

React employs a Virtual DOM for optimal performance;
Elements serve as the fundamental building blocks of React applications, representing UI components.

Components in React:

Components are self-contained, reusable pieces of UI;
Functional components are defined as JavaScript functions;
Components encapsulate their logic and rendering behavior.

Conditional Rendering:

React facilitates conditional rendering to display different UI components or content based on specified conditions;
Conditional rendering is achieved using JavaScript conditional statements such as && operator and the ternary operator ? ... : ....

Data Collection Rendering:

We use the map() method for iterating over arrays and dynamically rendering UI components for each item;
It's essential to assign a unique key prop to each element in the collection for efficient rendering.
