Several W3C Working Groups have since taken the lead in maintaining and continuing to develop standard APIs for the Web since then; HTML, SVG, CSS, or WebAPI being among them.

Performant JavaScript Best Practices - Level Up Coding Like any program, JavaScript programs can get slow fast if we aren’t careful with writing our code.

Not all scopes are made alike. jQuery GUI Manipulation – HTML5 Hive Basic knowledge of HTML5 and CSS3. Some exposure to JavaScript and jQuery is recommended but not required. In this tutorial, we will build a simple price calculator with HTML5 and CSS3. Then we will use jQuery to streamline the interface by the allowing the calculator’s only button to perform a simple calculation and reset the text fields.

The 10 Most Common Mistakes JavaScript Developers Make Today, JavaScript is at the core of virtually all modern web applications. The past several years in particular have witnessed the proliferation of a wide array of powerful JavaScript-based libraries and frameworks for single page application (SPA) development, graphics and animation, and even server-side JavaScript platforms. JavaScript has truly become ubiquitous in the world of web app development and is therefore an increasingly important skill to master. At first blush, JavaScript may seem quite simple. And indeed, to build basic JavaScript functionality into a web page is a fairly straightforward task for any experienced software developer, even if they’re new to JavaScript.

The Basics Of JavaScript Variable Definitions & Hoisting I wrote this tutorial as an introduction to an often overlooked subject. I can’t blame you, JavaScript is an accessible language — just pop open your text editor and you’re ready to start coding. But JavaScript has traditionally been a language of many quirks, oddball features and inconsistencies. Perhaps this article will be helpful to those who are completely new to the language. First things first.
