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.

  • Core JavaScript (ECMAScript)

  • Document Object Model (DOM)

  • Browser Object Model (BOM)

Core JavaScript (ECMAScript)

JavaScript supports mobile devices as well as desktop computers; this feature makes it a cross-platform scripting language. However, it is not much useful if used alone, which is why it is used along with server-side languages to make powerful and interactive applications. It can be easily integrated within a web browser environment, enabling users to have complete control over the browser's objects and events.

The core capabilities of JavaScript are also called ECMAScript. ECMAScript is not actually browser-dependent or environment-dependent. It is a set of core language elements that are used in different environments such as ScriptEase and Flash Action Script. Hence, we can say that ECMA Script contains...
