Download or read book A Tiny Introduction to JavaScript with Exercises and Puzzles written by Matthew MacDonald and published by . This book was released on 2020-11-24 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real coding for complete beginners. Join Matthew MacDonald, author of too-many-tech-books-to-count, as he enters the world of JavaScript-accompanied by friendly ninjas, cheating goblins, and at least one rude wizard. Develop your skills with 35 interactive exercises on CodePen. Best of all, there's no setup required (a web browser is all you need). Who needs another book about coding for kids? These days, you can't turn around twice without someone trying to teach you how to code. So why the heck did I write my own book? When my daughters started learning to code, I discovered that most tutorials were as dry as dust. If you wanted something more fun, you could play a coding game and write commands to move a character around a maze. But unlike real programming, there was no chance to be creative. There was no freedom. There was no invitation to build your own programs. Here's what makes this book different: Hands-on practice. If you want to learn a new skill, you need to practice. Otherwise, it's just a bunch of theory swimming around in your head. Friendly for beginners. If you're a beginner, it's not enough to learn the basics of a programming language like JavaScript. You also need to learn the concepts of programming at the same time. No setup required. The world is full of amazing frameworks, tools, and code editors. But who wants to install a bunch of software before you even get started? Tiny. I'm a programming nerd, so I like talking about things like Big O notation. But no one needs to be buried in theory at the start of their journey. In this book, every chapter is a bite-sized lesson that you can usually finish in one sitting. Kinda fun. Not everyone has the motivation to learn from an old-fashioned textbook. But who doesn't want to play dice with a cheating goblin? So I decided to make something of my own. Then I unleashed it on my family. This is the result of those experiments. Why JavaScript? JavaScript is a great first language for people learning to code. It's not because JavaScript is a great teaching language (it mostly isn't). It's because JavaScript is everywhere-on every operating system, every browser, and almost every electronic device that's more complicated than a toaster. That means you can effortlessly share your JavaScript programs with friends. Unlike all the rest of computing history, there's no downloading, installing, or configuring. And it doesn't hurt that JavaScript syntax is similar to many other professional languages, like Java and C#. That means the effort you spend to learn JavaScript is never wasted. Can adults read this book? Most certainly! However, this book assumes you're learning JavaScript and programming for the first time. If you already know a bit about programming, you'll probably prefer a guide that focuses on the JavaScript language without re-introducing the concepts you already know.

Download or read book The Pragmatic Programmer written by Andrew Hunt and published by Addison-Wesley Professional. This book was released on 1999-10-20 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: What others in the trenches say about The Pragmatic Programmer... “The cool thing about this book is that it’s great for keeping the programming process fresh. The book helps you to continue to grow and clearly comes from people who have been there.” — Kent Beck, author of Extreme Programming Explained: Embrace Change “I found this book to be a great mix of solid advice and wonderful analogies!” — Martin Fowler, author of Refactoring and UML Distilled “I would buy a copy, read it twice, then tell all my colleagues to run out and grab a copy. This is a book I would never loan because I would worry about it being lost.” — Kevin Ruland, Management Science, MSG-Logistics “The wisdom and practical experience of the authors is obvious. The topics presented are relevant and useful.... By far its greatest strength for me has been the outstanding analogies—tracer bullets, broken windows, and the fabulous helicopter-based explanation of the need for orthogonality, especially in a crisis situation. I have little doubt that this book will eventually become an excellent source of useful information for journeymen programmers and expert mentors alike.” — John Lakos, author of Large-Scale C++ Software Design “This is the sort of book I will buy a dozen copies of when it comes out so I can give it to my clients.” — Eric Vought, Software Engineer “Most modern books on software development fail to cover the basics of what makes a great software developer, instead spending their time on syntax or technology where in reality the greatest leverage possible for any software team is in having talented developers who really know their craft well. An excellent book.” — Pete McBreen, Independent Consultant “Since reading this book, I have implemented many of the practical suggestions and tips it contains. Across the board, they have saved my company time and money while helping me get my job done quicker! This should be a desktop reference for everyone who works with code for a living.” — Jared Richardson, Senior Software Developer, iRenaissance, Inc. “I would like to see this issued to every new employee at my company....” — Chris Cleeland, Senior Software Engineer, Object Computing, Inc. “If I’m putting together a project, it’s the authors of this book that I want. . . . And failing that I’d settle for people who’ve read their book.” — Ward Cunningham Straight from the programming trenches, The Pragmatic Programmer cuts through the increasing specialization and technicalities of modern software development to examine the core process--taking a requirement and producing working, maintainable code that delights its users. It covers topics ranging from personal responsibility and career development to architectural techniques for keeping your code flexible and easy to adapt and reuse. Read this book, and you'll learn how to Fight software rot; Avoid the trap of duplicating knowledge; Write flexible, dynamic, and adaptable code; Avoid programming by coincidence; Bullet-proof your code with contracts, assertions, and exceptions; Capture real requirements; Test ruthlessly and effectively; Delight your users; Build teams of pragmatic programmers; and Make your developments more precise with automation. Written as a series of self-contained sections and filled with entertaining anecdotes, thoughtful examples, and interesting analogies, The Pragmatic Programmer illustrates the best practices and major pitfalls of many different aspects of software development. Whether you're a new coder, an experienced programmer, or a manager responsible for software projects, use these lessons daily, and you'll quickly see improvements in personal productivity, accuracy, and job satisfaction. You'll learn skills and develop habits and attitudes that form the foundation for long-term success in your career. You'll become a Pragmatic Programmer.
