Develop real-time practical DApps using Ethereum and JavaScriptKey Features<ul>
<li>Create powerful, end-to-end applications for Blockchain using Ethereum</li>
<li>Write your first program using the Solidity programming language</li>
<li>Change the way you think and design your applications by using the all new database-Blockchain</li>
</ul>Book DescriptionBlockchain is a decentralized ledger that maintains a continuously growing list of data records that are secured from tampering and revision. Every user is allowed to connect to the network, send new transactions to it, verify transactions, and create new blocks, making it permission-less.
This book will teach you what Blockchain is, how it maintains data integrity, and how to create real-world Blockchain projects using Ethereum. With interesting real-world projects, you will learn how to write smart contracts which run exactly as programmed without any chance of fraud, censorship, or third-party interference, and build end-to-end applications for Blockchain.
You will learn about concepts such as cryptography in cryptocurrencies, ether security, mining , smart contracts, solidity, and more. You will also learn about web sockets, various API services for Ethereum, and much more.
The blockchain is the main technical innovation of bitcoin, where it serves as the public ledger for bitcoin transactions.What you will learn<ul>
<li>Walk through the basics of the Blockchain technology</li>
<li>Implement Blockchain's technology and its features, and see what can be achieved using them</li>
<li>Build DApps using Solidity and Web3.js</li>
<li>Understand the geth command and cryptography</li>
<li>Create Ethereum wallets</li>
<li>Explore consortium blockchain</li>
</ul>Who This Book is ForThis book is for JavaScript developers who now want to create tamper-proof data (and transaction) applications using Blockchain and Ethereum. Those who are interested in cryptocurrencies and the logic and database empowering it will find this book extremely useful.Table of Contents<ol>

Explore and master modern JavaScript techniques with ES2015 in order to build large-scale web applications About This Book * This course offers an expert's eye on the latest ES6 features and how these advanced tasks fit together in JavaScript as a whole * Discover robust JavaScript implementations of classic and advanced design patterns * Learn about modern web architectures and build real-world apps on top of them Who This Book Is For This course is for experienced developers familiar with other object-oriented languages who wants to learn new capabilities of ES-2015 to improve their web development skills and build professional-quality web applications. This also goes for those who want to explore some modern JavaScript features, techniques, and architectures in order to develop cutting-edge web applications. What You Will Learn * Get a run through of the basic language constructs, Functions, and Closures of JavaScript * Code using the powerful object-oriented feature in JavaScript * Master DOM manipulation, cross-browser strategies, and ES6 * Harness the power of patterns for tasks ranging from application building to code testing * Identify the best use cases for microservices * Gain expertise in responsive and dynamic website design * Enable real-time communications between client-client and client-server/server-client * Write complete applications using functional reactive programming In Detail JavaScript is a high-level, dynamic, untyped, lightweight, and interpreted programming language. Mastering modern JavaScript techniques and the toolchain are essential to develop web-scale applications. This Learning Path will upgrade your skills to ES2015, and you will get to introduce yourself to popular frameworks like React and Angular 2. In the first module, you will get familiar with the language constructs and how to make code easy to organize. You will gain a concrete understanding of variable scoping, loops, and best practices on using types and data structures, as well as the coding style and recommended code organization patterns in JavaScript. By the end of the module, you will understand how reactive JavaScript is going to be the new paradigm. Over the course of the next module, you will explore how design patterns can help you improve and organize your JavaScript code. You'll get to grips with creational, structural, and behavioral patterns and get a deeper look at patterns used in functional programming, as well as model view patterns and patterns to build web applications. By the end of the module, you'll be saved of a lot of trial and error and developmental headaches, and you will be on the road to becoming a JavaScript expert. In the last leg of this course, you will shift your focus to network programming concepts as you build a real-time web application with websockets. Along the way, you'll explore how the power of JavaScript can be increased multi-fold with high performance techniques. By the end of this module, you'll be a skilled JavaScript developer with a solid knowledge of the latest JavaScript techniques, tools, and architecture to build modern web apps. This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products: * Mastering JavaScript by Ved Antani * Mastering JavaScript Design Patterns, Second Edition by Simon Timms * Modern JavaScript Applications by Narayan Prusty Style and approach This course is a comprehensive guide with a clear focus on practical use cases and patterns. Each chapter consists of best practices, useful advice, and a bunch of easy-to-follow examples that will build up your skills as you advance.
