Components Overview
Explains that components are the building blocks of a React application, allowing complex applications to be built by nesting components. It covers the difference between functional and class-based components.
File Extensions
Discusses how React components are usually declared in files ending with .jsx or .js extensions. The .jsx extension indicates the file contains JSX.
Functional Components
Provides a simple example of a functional component in React that returns JSX, explaining the syntax and structure.
Named Export
Allows exporting of multiple components from a single file using syntax like `export const MyComponent = () => {}`. Components can then be imported using syntax like `import { MyComponent } from './MyComponent';`.
Default Export
Allows exporting a single component from a file using syntax like `export default MyComponent`. This allows the component to be imported without curly braces.
Class Components Explanation
Provides an overview of how class components in React work, including how they take parameters called props and return JSX as output.
Exporting Class Components
Explains how to keep React code organized by defining components in different ways, including named export and default export, with code examples for both methods.
Named Export Usage
Offers a syntax guide for exporting multiple components from a single file using named exports.
Default Export Usage
Provides a syntax guide for exporting a single component from a file using default exports.
UseState Hook
Explains how to use the useState hook in React functional components to manage state.
Props vs State Comparison
Compares props and state, explaining that props are immutable and passed to components as parameters, while state is managed within the component.
Functional Component State
Describes how state is managed in functional components using the useState hook, and includes examples.
Event Handling Tutorial
Guides users on how to handle events in React, such as button clicks and input typing. It contrasts React's event handling with basic HTML.
Code Example
Provides code snippets for adding event handlers in a React component, showing how to define a function and pass it as a prop.
Conditional Rendering JSX
Learn how to conditionally render components in React using JavaScript syntax. This includes using if statements, &&, and ?: operators.
PackingList Component Example
A practical example is provided where a PackingList component renders several Item components. Each Item can be marked as packed or not using the isPacked prop.
If/Else Statement Example
Explanation on how to implement an if/else statement for conditional rendering. It guides you on adding conditional logic to JSX components.
Rendering Lists
Teaches how to render lists in React using the map() method. It explains the importance of efficiently displaying data in list formats with React.js, and using unique keys for each element.
Inline Styles
Allows applying CSS styles directly to React components by setting the style prop as an object where keys are camelCase style properties.
Global Styles
Enables styling of components by defining styles that apply to the entire application or sections of it, typically written in global CSS files.
CSS Modules
A styling method where each component is associated with a CSS file. The styles are locally scoped to the component using a unique identifier to prevent naming conflicts.
Controlled Forms
Forms in React where data is handled by the component's state. Users must know about state management before using controlled forms.
Uncontrolled Forms
Forms where the DOM handles the data using references like useRef. Data is accessed directly from the form elements.
State Management
Important for controlled forms. Used to manage input values within forms. Uses useState to handle and update values.
