Core Concepts to Master
Components
React components are the building blocks of a React application. They can be thought of as reusable pieces of code that are used to render UI elements. Components can be function-based or class-based and can have their own state and lifecycle methods.
State and Props
State and props are used to manage data in a React application. State is used to store data that changes over time, while props are used to pass data from a parent component to a child component. Understanding how to manage state and props is crucial in building React applications.
JSX
JSX is a syntax extension for JavaScript that allows developers to write HTML-like code in their JavaScript files. JSX is used to render UI elements in a React application and is a key feature of the React framework.
