Before we can embark on our React.js
journey, we need to set up our development
environment. In this chapter, we will guide
you through the process of installing Node.js
and npm, which will serve as the foundation
for our React.js projects. We will then
demonstrate how to create a new React
project using tools like Create React App
and set up a local development server. By
the end of this chapter, you will have a fully
functional development environment ready
to build React applications.

JSX is a powerful syntax extension for
JavaScript that allows us to write HTML-like
code within our JavaScript files. In this
chapter, we will explore JSX in depth and
understand how it facilitates the creation of
dynamic and reusable UI components. We
will learn how to write JSX code, embed
JavaScript expressions, and use conditional
rendering and looping techniques.
Additionally, we will cover the process of
transpiling JSX code into plain JavaScript
using tools like Babel.

React is all about components. In this
chapter, we will delve into the world of React
components, understanding their role in
building complex user interfaces. We will
explore two types of components: functional
components and class components. You will
learn how to create, nest, and compose
components to create reusable and modular
code. Furthermore, we will dive into the
concept of props, which enables us to pass
data from parent components to child
components.

State and props are crucial concepts in
React.js that allow us to manage and
manipulate data within our components. In
this chapter, we will explore the component
states and understand their significance in
creating dynamic and interactive UIs. You
will learn how to set and update state using
the setState method, both in class
components and functional components
using React Hooks. Additionally, we will
explore the concept of props and how to
pass data between components effectively.

Interactivity is a fundamental part of
modern web applications. In this
chapter, we'll discover how to
handle events in React.js and
respond to user interactions. We'll
learn how to set up event handlers
and work with forms, including
controlled components for capturing
user input and form validation
techniques.

Building single-page applications
often requires managing multiple
views and navigation. In this
chapter, we'll introduce React
Router, a popular library for
handling routing in React.js. We'll
learn how to set up routes, handle
route parameters, and create nested
routes to build complex navigation
structures.

Most real-world applications require
fetching data from APIs. In this
chapter, we'll explore different
approaches for making API requests
in React.js. We'll cover asynchronous
JavaScript techniques and utilize the
'use effect' hook to fetch data from
APIs. We'll also handle loading states
and errors gracefully.
