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.

While in some languages, to create an object we have to do a lot of groundwork, such as creating classes and defining constructors, in JavaScript, and by extension in TypeScript, we can just create the object as a literal. So, if we want to create a person object, with firstName and lastName properties, we only need to write the following:

const person = {
    firstName: "Ada",
    lastName: "Lovelace"
}

JavaScript makes it easy to create and use the object, just like any other value. We can access its properties, pass it as an argument into methods, receive it as a return value from functions, and so on. And because of JavaScript's dynamic nature, it's very easy to add properties to our object. If we wanted to add an age property to our object, we could just write the following:

person.age = 36;
