		<description><![CDATA[Oracle is putting its weight behind a new project aimed at making JavaScript work better with Java. Dubbed Project Nashorn, its goal is “to implement a lightweight high-performance JavaScript runtime in Java with a native JVM.”]]></description>
		<content:encoded><![CDATA[You can check out details of the project here. Announced late last month, Project Nashorn boasts Jim Laskey from Oracle as the lead. The plan involves starting from scratch, using entirely new code. The initial source for it will come from an internal Oracle project. When complete, the project is supposed to let Java programmers embed JavaScript in Java apps using JSR-223 and develop freestanding JavaScript apps using the jrunscript command line.  So what will go into this project? Oracle's John Coomes, who posted the new project, explained that  The scope of this project will include, but is ...]]></content:encoded>

		<description><![CDATA[Earlier this week, Tumblr fell victim to a fast-spreading virus that affected logged-in users who viewed infected blog pages. The company was forced to temporarily suspend the ability of site users to post in order to get the JavaScript virus under control and clean it from the website.]]></description>
		<content:encoded><![CDATA[The malware went viral on December 3. Tumblr users viewing an infected post, if they were logged in, would discover that a racist rant has been published to their own account automatically by the malicious code. Initially, Tumblr's engineers tweeted that they had resolved the issue and that it had not spread very widely, affecting only a few thousand Tumblr blogs.  That turned out not to be the case, as Sophos, a security firm, later discovered. Investigating the malware with some information it acquired from an infected account, Sophos found a block of JavaScript that had been scrambled to hi...]]></content:encoded>

<link>https://www.devarticles.com/c/a/JavaScript/Google-Releases-Stable-Dart-Version-JavaScript-Rival/</link>
		<description><![CDATA[After more than a year of work, Google finally released the first stable version of Dart, the scripting language it hopes will take the place of JavaScript. Though the search giant also unveiled plenty of other goodies to go along with Dart, the company faces an uphill battle for the language's adoption.]]></description>
		<content:encoded><![CDATA[What kind of inducements does Google offer for those interested in creating web-based applications in Dart? For starters, there's Dartium, a Chromium-based browser that includes the Dart virtual machine (DVM). Programmers can use it to test Dart web applications directly, without compiling to JavaScript until they need to test them on other browsers. Keep in mind that Dartium is a technical preview, and users are warned right at the top of the download page not to use Dartium as their primary browser. So what do you do when you're ready to run your Dart app on a browser without a DVM? The Dart...]]></content:encoded>

		<description><![CDATA[Imagine that you can type some JavaScript code on one side of your screen, and immediately see what it does on the other side. Imagine that you can make changes to this code and see the effect instantly, without having to recompile. The Khan Academy did – and built an interface that accomplishes this task.]]></description>
		<content:encoded><![CDATA[You've probably heard of the Khan Academy as a online not-for-profit organization with the mission of providing a free world class education to anyone everywhere. They boast more than 3,000 instructional videos on their website covering a wide range of topics. They're particularly strong in math, going all the way from 1+1=2 through calculus. They take a hands-on approach to learning, and now they're applying it to computer science.

		<description><![CDATA[While many users enjoy accessing the Internet through their iPhone or iPad, some may have noticed a certain disparity in the speed of certain browsers or applications. That's not endemic to the products; in fact, it has a lot more to do with something called Nitro. Fortunately, there's an app called Nitrous that can help those with the need for speed.]]></description>
		<content:encoded><![CDATA[If you've developed any applications for Apple's official App Store, you know that the company's Mobile Safari browser has something that third-party apps don't. As Paul Morris explains,  when Mobile Safari was revamped...with it came a rebuild of the underlying code around the Nitro JavaScript engine that drastically increased performance and provided the user with a browsing experience that contained fewer lags and pauses while visiting their favorite websites. In a rather bitter sweet twist, Apple unfortunately doesn't allow apps built around the UIWebView to take advantage of this newer en...]]></content:encoded>

<link>https://www.devarticles.com/c/a/JavaScript/JQuery-20-Leaving-Older-IE-Versions-Behind/</link>
		<description><![CDATA[Late last month, the developers working on the jQuery core noted that the beloved JavaScript library would be “undergoing a spring cleaning to remove insecure, inefficient, ineffective, and inadvisable features.” Along with some great customization options, they noted a major change for jQuery 2.0: the library would no longer support older versions of the Internet Explorer browser.]]></description>
		<content:encoded><![CDATA[The versions of IE that jQuery 2.0 will not support include 6, 7 and 8. You can check the full blog entry, which provides details of the planned development path. But don't panic; just because jQuery 2.0 won't support those old browsers doesn't mean that the library will stop supporting them altogether. First, keep in mind that the current version of jQuery is 1.8. jQuery 2.0 isn't scheduled to come out until early 2013. A little before jQuery 2.0, the developers will come out with jQuery 1.9. In this version of the library,  We'll remove many of the interfaces already deprecated in version 1....]]></content:encoded>

		<description><![CDATA[When rendering anything on a browser, it's all about speed, and that's as true for JavaScript as it is for anything else. So when InfoWorld decided to measure how quickly several web browsers handled JavaScript based on one of the accepted benchmark tests, it's only natural that the results would be of interest. But the winner was a surprise.]]></description>
		<content:encoded><![CDATA[You can check out the full article, written by Woody Leonhard. He used the SunSpider 0.9.2 JavaScript benchmark. He acknowledges that this is not an unbiased tool. After all, it's made by Apple, and Apple is far from fair when it comes to any browser other than its own Safari. Leonhard noted that  non-Apple browsers are all forced to use a slow rendering class known as UIWebView, while Safari gets to run its Nitro version of JavaScript.   Given that, you'd expect anything other than Safari on one of Apple's operating systems to run as slow as molasses. And Leonhard's initial tests supported th...]]></content:encoded>

		<description><![CDATA[No, the software giant isn't embracing new-age practices for the next version of its browser. Microsoft's new JavaScript engine, dubbed Chakra, was introduced in Internet Explorer 9. It will be updated for IE 10. Let's take a look at what's coming.]]></description>
		<content:encoded><![CDATA[According to Mary Jo Foley, writing for ZDNet,  Chakra is still alive and well in IE10, and will be part of the one HTML5 browsing engine that will power both the Metro-Style and Desktop in Windows 8 and Windows RT.  Since any web browser's JavaScript engine strongly impacts its performance, it behooves developers to know what's changing in the next version.  In its blog post on the subject, Microsoft describes the increasing performance burden borne by web browsers since the early days of the Internet. With the change from static content in the early days to the kind of interactivity that AJA...]]></content:encoded>

<link>https://www.devarticles.com/c/a/JavaScript/Brendan-Eich-We-Dont-Need-Google-Native-Client/</link>
		<description><![CDATA[JavaScript founder Brendan Eich expressed his skepticism concerning Google Native Client. Speaking late last month at the O'Reilly Fluent Conference in San Francisco, Eich explained that JavaScript could easily serve the same needs that Native Client is being designed to fill – and JavaScript already boasts wider vendor support than Native Client could hope for.]]></description>
		<content:encoded><![CDATA[Eich was at the conference in part to promote ECMAScript 6, the next upgrade to the official JavaScript specification. Google's Native Client, an open source solution, is designed to run portable native code securely in a browser. JavaScript has been doing this ever since it was first created, 17 years ago. What's more, JavaScript is widely supported by browser vendors such as Apple, Microsoft, and Mozilla. Google might find it difficult to get such widespread support for Native Client; the search giant also makes Chrome, a competing web browser. In his talk, Eich noted JavaScript's accessibil...]]></content:encoded>

		<content:encoded><![CDATA[What is a JavaScript Variable? If you are completely new to working with JavaScript, you may find it difficult to understand at first.  As with any learning process, you have to start with the basics.  This is especially true with programming and the like, because each language can be thought of as its own little universe complete with unique terms, rules, and more.   So, when discussing variables in JavaScript, it probably helps to compare them to other parts of life.  Before we do that, let us describe what variables are.  One of the most basic ways to describe a variable in JavaScript is to...]]></content:encoded>
