Introduction to React Section Sum-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.
