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.

Boolean Operators

Boolean operators are operators that, when combined into an expression, return a Boolean value. Most Boolean operators are "binary" operators that accept two values, each of which sit either side of the operator. Like other operators, each value can be an expression and can be of any value type. As Boolean operators themselves form expressions, they can be used as input to other Boolean operators.

Boolean operators fit into two categories; namely, comparison operators and logical operators.

Comparison Operators

Comparison operators are used for comparing one value, or the result of an expression, with another. The operator in this circumstance may be considered a rule. If the rule succeeds, then the response of the combined expression returns true. Otherwise, it returns false.

Comparison operators include the following symbols:
