    This book was borne out of frustration. I have been in software engineering for many years, and when I started learning Node.js and Backbone.js, I learned the hard way that their official documentation and the Internet lack in quick start guides and examples. Needless to say, it was virtually impossible to find all of the tutorials for JS-related modern technologies in one place.

    The best way to learn is to do, right? Therefore, I've used the approach of small simple examples, i.e., quick start guides, to expose myself to the new cool tech. After I was done with the basic apps, I needed some references and organization. I started to write this manual mostly for myself, so I can understand the concepts better and refer to the samples later. Then StartupMonthly and I taught a few 2-day intensive classes on the same subject -- helping experienced developers to jump-start their careers with agile JavaScript development. The manual we used was updated and iterated many times based on the feedback received. The end result is this book.

    What to Expect

    A typical reader of RPJS should expect a collection of quick start guides, tutorials and suggestions (e.g., Git workflow). There is a lot of coding and not much theory. All the theory we cover is directly related to some of the practical aspects, and essential for better understanding of technologies and specific approaches in dealing with them, e.g., JSONP and cross-domain calls.

    In addition to coding examples, the book covers virtually all setup and deployment step-by-step.

    You'll learn on the examples of Chat web/mobile applications starting with front-end components. There are a few versions of these applications, but by the end we'll put front-end and back-end together and deploy to the production environment. The Chat application contains all of the necessary components typical for a basic web app, and will give you enough confidence to continue developing on your own, apply for a job/promotion or build a startup!

    Who This Book is For

    The book is designed for advanced-beginner and intermediate-level web and mobile developers: somebody who has been (or still is) an expert in other languages like Ruby on Rails, PHP, Perl, Python or/and Java. The type of a developer who wants to learn more about JavaScript and Node.js related techniques for building web and mobile application prototypes fast. Our target user doesn't have time to dig through voluminous (or tiny, at the other extreme) official documentation. The goal of Rapid Prototyping with JS is not to make an expert out of a reader, but to help him/her to start building apps as soon as possible.

    Rapid Prototyping with JS: Agile JavaScript Development, as you can tell from the name, is about taking your idea to a functional prototype in the form of a web or a mobile application as fast as possible. This thinking adheres to the Lean Startup30 methodology; therefore, this book would be more valuable to startup founders, but big companies' employees might also find it useful, especially if they plan to add new skills to their resumes.

    What This Book is Not

    Rapid Prototyping with JS is neither a comprehensive book on several frameworks, libraries or technologies (or just a particular one), nor a reference for all the tips and tricks of web development. Examples similar to ones in this book might be publicly available online.

    Even more so, if you're not familiar with fundamental programming concepts like loops, if/else statements, arrays, hashes, object and functions, you won't find them in Rapid Prototyping with JS. 

     Communication technologies are constantly advancing to keep up with the times. Messaging apps are huge right now. Completely overtaking social media by becoming the primary way we communicate online.


    When most entrepreneurs are starting out, they like to read articles on “how to make a killing with your first app,” “building the multi-billion dollar app” and most books related to this topic. They are glued to this side of the story and blinded to the other. To have your own success story you have to find out why other apps fail. The painful truth is there are more failed apps than successful ones.

    Many people have tried using social media to grow their business and create a passive income but failed. Places like Facebook and twitter are Goldmines for entrepreneurs but only few people are able to use the right strategies to create a good following and the reoccurring purchases and traffic. This is because the less you know about the right strategies, the less competition the gurus have to deal with.


    Facebook for Business have revealed several ways to optimize Facebook traffic, secure reoccurring costumers and sell the right products to the right people. This involves different income generation methods that can lead to a reoccurring and growing stream of profit. You will be shown exactly how one of these methods generated over $2000 on a single Facebook account within few weeks.


    Odessa Berry, owner of a Pet Clinic in New York used one of these methods and made in 2 months what she used to make in a year.


    After reading just the First and Second Chapters of this book you will start to see Facebook in a different way, to use each and every feature for boosting your income on a daily basis.


    For example, in Chapter 8, The Facebook Killer ROI method was used last week to reach 1.9 million users with the simple tweak listed, which generated over 17,800 sales on a single product. Today you can take advantage of this new tweak and independently create the life you want.

    Preface 

    If you have always wanted to have a website, there is no better time to achieve your dream than now. Due to advancements in web designing, you do not need to spend years learning HTML; “drag and drop” website builders make everything easy for newbies. Sweetening the deal even further, you can create your website without spending a penny. 

    However, the difficult part is finding a good provider that will let you make a decent free website. As you may know, “free” usually comes at a cost. In this book, not only will I show you how to create a website, but I will also recommend some of the best free website providers you can sign up with. 

    Anyone who has ever started a website knows that making it is easy. But, finding motivation to keep it going is the most difficult part. So, I will also give you tips you can follow to keep on creating content. Furthermore, there are sections in the book dealing with website promotion, SEO, and other topics. 

    Since the internet can be dangerous to young people, I recommend that you communicate to your parents or guardians about your intentions to make a free website. It's even better if they take part in the whole process. 

    So without further ado, let's get started.
