Introduction

Learn JavaScript: Beginners Guide will teach you the basics of programming and JavaScript. Whether you are an experienced programmer or not, this book is intended for everyone who wishes to learn the JavaScript programming language. This book is divided into three main parts. The first 14 chapters cover the JavaScript language. The following four chapters discuss how JavaScript is used to program web browsers. The final two chapters are miscellaneous, and exercises. Various important topics and cases related to JavaScript programming are described in the Miscellaneous chapter, which is followed exercises.

Code, and what to do with it

Code is the written instructions that make up a program. Many chapters in this book contain a lot of code, and it is important to read and write code as part of learning how to program. You should not just quickly scan the examples - read them carefully and try to understand them. This may be difficult at first, but with practice, you will improve. The same goes for the exercises - make sure you actually try to write a solution before assuming you understand them. It is also helpful to try running your solutions to the exercises in a JavaScript interpreter, as this will allow you to see if your code is working correctly and may encourage you to experiment and go beyond the exercises.

Typographic conventions

In this book, text written in a monospaced font represents elements of a program. This can be a self-contained fragment or a reference to part of a nearby program. Programs, like the one shown below, are written in this way:

const numbers = [45, 4, 9, 16, 25];
let txt = "";
for (let x in numbers) {
  txt += numbers[x];
}

Sometimes, the expected output of a program is written after it, preceded by two slashes with a Result, like this:

console.log(txt);

// Result: txt = '45491625'
