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.

Working with Strings

Like numbers, strings are simple immutable data types that are managed within the JavaScript runtime as a list of binary values, which are representable as characters. Since they are immutable, they cannot be altered. If you modify a string, using one of the various methods provided, you are actually creating a new string with the changes applied.

The literal representation of strings is a list of characters surrounded by quotes. These quotes can be double quotes, single quotes (apostrophes), or backticks:

console.log( "I am a string" );
console.log( 'I am also a string' );
console.log( `I am a special string` );

Strings can be thought of as a long list of single characters, much like arrays, which will be discussed later. As such, it is possible to query individual, or groups of, characters:

["H", "e", "l", "l", "o", ",", " ", "W", "o&quot...
