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.

Data Types

Programming is all about manipulating data. Data can represent values such as people's names, temperature, image dimensions, the amount of disk storage, and total likes on a discussion group post.

All the data in a program has a data type. The data types that you usually learn to use first in JavaScript are number, string, boolean, object, array, and function. The number, string, and Boolean data types represent a single value. Objects represent more complex data. Functions are for writing programs.

Some common JavaScript data types with their uses and descriptions are as follows:

  • number: Any positive or negative value whole numbers, usually called integers and floating-point numbers, that can be used in mathematical operations. It is used in product prices, checkout totals, the number of likes on a post, the geometry value of Pi, and can be used as a random number.
  • string: Any set of valid characters that cannot be, or are not intended to be...
