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.

Fixed Types

Fixed types are types that have no variation of value. Unlike numbers, which may have any combination of digits, an optional minus sign (for negative numbers), a decimal point, or a scientific notation, a fixed type is always one simple value or value group.

In JavaScript, the available fixed types include null, undefined, and Booleans (true and false). These values are static and cannot change. If a variable contains one of these values, it is then strictly equal to the value itself. Fixed types are more of a representation of a situation than actual data. For instance, true is a fixed representation of truthfulness and false is a fixed representation of falsehood. The values are not quantifiable in the real world but are representative of logic that software directly deals with.

The null Value

null, in mathematical terms, denotes a value that is not present. In JavaScript, null is a static value that's used to mean no value. In other languages, this would...
