Web Developer's Reference Guide

By: Joshua Johanan, Talha Khan, Ricardo Zea

Overview of this book

This comprehensive reference guide takes you through each topic in web development and highlights the most popular and important elements of each area. Starting with HTML, you will learn key elements and attributes and how they relate to each other. Next, you will explore CSS pseudo-classes and pseudo-elements, followed by CSS properties and functions. This will introduce you to many powerful and new selectors. You will then move on to JavaScript. This section will not just introduce functions, but will provide you with an entire reference for the language and paradigms. You will discover more about three of the most popular frameworks today—Bootstrap, which builds on CSS, jQuery which builds on JavaScript, and AngularJS, which also builds on JavaScript. Finally, you will take a walk-through Node.js, which is a server-side framework that allows you to write programs in JavaScript.

Netscape submitted JavaScript to European Computer Manufacturers Association(ECMA) for standardization and specification. The standardized version was named ECMAScript. ECMAScript is a trademarked scripting language specification standardized by ECMA International.

The ECMAScript V5 introduced a new mode called the strict mode; this brought forward better and thorough error checking to avoid constructs that cause errors. Many ambiguities from the third version were removed and real-world implementations were added.

The ECMAScriptV6 added plenty of new syntax for writing complex programs. It introduced classes and modules extending the semantics from V5. Iterators were...
