Mastering The Faster Web with PHP, MySQL, and JavaScript

By: Andrew Caya

Overview of this book

This book will get you started with the latest benchmarking, profiling and monitoring tools for PHP, MySQL and JavaScript using Docker-based technologies. From optimizing PHP 7 code to learning asynchronous programming, from implementing Modern SQL solutions to discovering Functional JavaScript techniques, this book covers all the latest developments in Faster Web technologies. You will not only learn to determine the best optimization strategies, but also how to implement them. Along the way, you will learn how to profile your PHP scripts with Blackfire.io, monitor your Web applications, measure database performance, optimize SQL queries, explore Functional JavaScript, boost Web server performance in general and optimize applications when there is nothing left to optimize by going beyond performance. After reading this book, you will know how to boost the performance of any Web application and make it part of what has come to be known as the Faster Web.

Chapter 7. JavaScript and Danger-Driven Development

"In JavaScript, there is a beautiful, elegant, highly expressive language that is buried under a steaming pile of good intentions and blunders."                                                       –  Douglas Crockford, JavaScript: The Good Parts

This quotation expresses essentially what optimizing JavaScript code is all about.

Often fascinated by the latest shiny feature or by the need to deliberately or pretentiously display his own abilities, the developer's mind sometimes slips into a mysterious state of awaken sleep by which he is overcome by the need to show off overly complex code or by the desire to use the most recent features even though he knows, deep down, that this means that he will have to sacrifice long-term stability and the efficiency of his computer program. This way of building applications is what we might call "Danger-Driven Development". JavaScript has many very bad parts but has enough good parts to outweigh the bad...
