1. Getting Started

The prompt provides a list of terms that are commonly used in React, a popular JavaScript library for building user interfaces. The terms include React, component, virtual DOM, JSX, constructor() method, render() method, state, setState() method, props, and binding methods. The prompt does not provide any additional context or information about these terms.

What is a Component?

State and setState()

Props (properties)

Binding Methods

2. Lifecycle Methods

Now that we have become familiar with most of the React basics and how components work and integrate into the development of a website. Since we know that React components are loaded onto the main page and then can be dynamically updated which means that they go through a certain cycle of stages that can be intervened in and the behavior can be updated. This cycle can be manipulated through what are called lifecycle functions at different stages. React class component lifecycle methods are used for a variety of purposes, including performing setup tasks when a component is first rendered, updating a component in response to changes in props or state, and cleaning up any resources that the component is using.

componentWillMount()

componentWillUnmount()

componentDidMount()

shouldComponentUpdate()

componentDidUpdate()

componentDidCatch()

Overview of Component Lifecycle

3. Functional Components and Hooks

Now that we have gone over the basics of class-based components, we will now explore a better and more concise way to write React components with functional components which are a lot more commonly used in React these days. Functional components are a way to define components in React that are simple, lightweight, and only consist of a render function. They are a great choice for simple, presentational components that only need to render some JSX and don't have their own state or lifecycle methods. In this section of the course, we'll look at how to use functional components with Hooks to manage state and other lifecycle events.

4. Advanced Topics

Now, we understand the basics of React with regards to the various kinds of components available and how to use them and exploit their lifecycle to our advantage in a webpage, we will now move on to some advanced topics. These topics will deal with topics like state management through Context API and the Consumer and Provider architecture in React and how these things make life easier in a production-level React App. Then we will move onto Routing in react and how it all works to produce a navigable React App without having to reload the page. This involves studying an important React package called “react-router-dom” which we will get into in this section.

React Router Dom

react-router-dom is a library that provides a set of components and functions for building routing into a React application. It is part of the react-router family of libraries, which provide a flexible and powerful way to handle routing in React applications.

Routing refers to the process of determining which content to display based on the current URL of an application. In a React application, this is typically achieved by setting up a set of routes that map specific URL patterns to components or pages.

Router: This is the top-level component that provides a context for routing in a React application. There are several different types of routers available, including BrowserRouter, HashRouter, and MemoryRouter, each of which is designed to work with a different type of environment.
Switch: This component is used to group a set of Route components and render the first one that matches the current URL. It is typically used to define a set of routes that should be exclusive to each other, meaning only one route will be active at a time.
Route: This component defines a single route in a React application. It specifies a path prop that determines which URL patterns it should match, and a set of components to render when the route is active. The exact prop can be used to specify that the route should only be considered active when the entire URL matches the path exactly.

Here is a basic example of how you might use react-router-dom to set up routing in a React application:

In this example, the Router component is used to wrap the entire application and provide a context for routing. The Switch component is used to group a set of Route components, which define the different routes in the application.

Each Route component specifies a path prop that determines which URL patterns it should match, and a set of components to render when the route is active. The exact prop can be used to specify that the route should only be considered active when the entire URL matches the path exactly.
