Overview of this book

If you're looking for a programming language to develop flexible and efficient apps, JavaScript is a great choice. However, while offering real benefits, the complexity of the entire JavaScript ecosystem can be overwhelming. This Workshop is a smarter way to learn JavaScript. It is specifically designed to cut through the noise and help build your JavaScript skills from scratch, while sparking your interest with engaging activities and clear explanations. Starting with explanations of JavaScript's fundamental programming concepts, this book will introduce the key tools, libraries and frameworks that programmers use in everyday development. You will then move on and see how to handle data, control the flow of information in an application, and create custom events. You'll explore the differences between client-side and server-side JavaScript, and expand your knowledge further by studying the different JavaScript development paradigms, including object-oriented and functional programming. By the end of this JavaScript book, you'll have the confidence and skills to tackle real-world JavaScript development problems that reflect the emerging requirements of the modern web.

The TypeScript Language

TypeScript is an interesting and important alternative to the JavaScript language. A superset of the JavaScript language, TypeScript was developed by Microsoft and was released sometime in 2014. It is very similar to JavaScript but has a feature that is very important to some: strict typing with type inference.

Strict typing is where a variable has a fixed type. This may be a number, a string, or a Boolean. By being strictly typed, a variable is unable to contain a value of any other type. This prevents a number of bugs in your system.

Let's look at a JavaScript problem.

A developer builds a function that accepts two numbers and adds them together:

function add(a, b) {
if (a && b && a + b) {
    return a + b;
  } else {
    throw "invalid parameters passed to 'add' function";
  }
}

Now, the developer has thought to check the parameters, first,...
