Overview of this book

By learning TypeScript, you can start writing cleaner, more readable code that’s easier to understand and less likely to contain bugs. What’s not to like? It’s certainly an appealing prospect, but learning a new language can be challenging, and it’s not always easy to know where to begin. This book is the perfect place to start. It provides the ideal platform for JavaScript programmers to practice writing eloquent, productive TypeScript code. Unlike many theory-heavy books, The TypeScript Workshop balances clear explanations with opportunities for hands-on practice. You’ll quickly be up and running building functional websites, without having to wade through pages and pages of history and dull, dry fluff. Guided exercises clearly demonstrate how key concepts are used in the real world, and each chapter is rounded off with an activity that challenges you to apply your new knowledge in the context of a realistic scenario. Whether you’re a hobbyist eager to get cracking on your next project, or a professional developer looking to unlock your next promotion, pick up a copy and make a start! Whatever your motivation, by the end of this book, you’ll have the confidence and understanding to make it happen with TypeScript.

Preface

React Components

Now let's dig into how these components work. There are several different ways to declare a component in React. You even have the choice to use JSX or not. This book will focus on creating components with function expressions, but we'll go over a few other patterns, so you'll know them when you see them.

Class Components

This style of component follows a classical (that is, relating to the programming concept of classes) pattern of component declaration. Many older examples will use class components, but they have fallen largely out of fashion due to being more verbose than other patterns. To create a class component, we import the Component class from React and extend it while creating our own class:

import React, { Component } from 'react';
interface Comp1Props {
  text: string;
}
export default class Comp1 extends Component<Comp1Props> {
  render() {
    const { text } = this.props;...
