In programs, variables hold values (like the number 42) to be used by the program. The characters a and b are called variables (see 'Variables'), which are like simple boxes you can store any of your stuff in. In JavaScript, a statement might look as follows: In a computer language, a group of words, numbers, and operators that performs a specific task is a statement. The rules for valid format and combinations of instructions is called a computer language, sometimes referred to as its syntax, much the same as English tells you how to spell words and how to create valid sentences using words and punctuation. Usually code is saved in a text file, although with JavaScript you can also type code directly into a developer console in a browser, which we'll cover shortly. If you're already fairly comfortable with JavaScript, first check out Chapter 3 as a brief glimpse of what to expect from YDKJS, then jump right in! CodeĪ program, often referred to as source code or just code, is a set of special instructions to tell the computer what tasks to perform. Chapter 2 introduces what JavaScript is about, but again, it's not a comprehensive guide - that's what the rest of the YDKJS books are for! Once you feel comfortable with general programming basics, Chapter 2 will help guide you to a familiarity with JavaScript's flavor of programming. There are also many other fantastic programming introduction resources that can help you dig into these topics further, and I encourage you to learn from them in addition to this chapter. It's mostly intended if you are starting YDKJS with little to no prior programming experience, and are looking to these books to help get you started along a path to understanding programming through the lens of JavaScript.Ĭhapter 1 should be approached as a quick overview of the things you'll want to learn more about and practice to get into programming.

This book starts off explaining the basic principles of programming at a very high level. Especially if you're just getting into programming and/or JavaScript, this book will briefly explore what you need to get up and going.

Up & Going is an introduction to several basic concepts of programming - of course we lean toward JavaScript (often abbreviated JS) specifically - and how to approach and understand the rest of the titles in this series. Welcome to the You Don't Know JS ( YDKJS) series. You Don't Know JS: Up & Going Chapter 1: Into Programming
