I recently did a google search for "javascript clone", and noticed there's a lot of confusion about cloning vs. copying out there. Every function called clone() I found was in fact either a shallow or deep copy. - Premasagar Rose

jQuery makes it pretty easy to manipulate client side elements, so it’s not all that often that I think about using something like client side templating to get content loaded into pages. However, recently I have been working on a few apps that had fairly complex list based layouts and it started getting tedious to use manual code to update all the items. Further doing it by hand can be brittle if your layout changes as you have to keep the layout and the update code in sync. Templating can address this problem by letting you use templates that describe your output with ‘holes’ that are filled in with data when the template is processed. Templating is a good solution in a few scenarios: Loading all data from the server especially in rich list displays Adding or updating new items in lists Anywhere you need to add new complex content to the page Anything that requires client side HTML rendering - Premasagar Rose

Once upon a time, all we needed to worry about was reducing Bytes and Requests and playing around with load order to make things faster. Nowadays, we are increasingly impacting one more major component in performance - CPU utilization. Using jQuery and other frameworks that make selecting nodes and DOM manipulation easy can have adverse affects if you’re not careful and follow some simple practices for reducing the work the browser has to do. - Premasagar Rose

John Resig's JavaScript classical-inheritance-simulating code. Based on implementations employed by Base2 and Prototype. * Creating a constructor is simple (by providing an 'init' method) * To create a new 'class' you extend (sub-class) an existing class * All of the 'classes' inherit from a single ancestor: Class * Access to overridden methods is provided (with their context properly set) E.g. var Person = Class.extend({ init: function(isDancing){ this.dancing = isDancing; }, dance: function(){ return this.dancing; } }); var Ninja = Person.extend({ init: function(){ this._super( false ); }, dance: function(){ // Call the inherited version of dance() return this._super(); }, swingSword: function(){ return true; } }); - Premasagar Rose

a new collaborative community site for video creators to ask questions and offer answers for anything related to video production— cameras, editing, publishing, and more. We think this will be an extremely useful site for the video community at large. We think WTF really sums up how we feel when we’re stuck on with a camera or editing problem. The site is based on the StackOverflow service, so we think it’ll work well. - Premasagar Rose

WebWait is a website timer. Use WebWait to benchmark your website or test the speed of your web connection. Timing is accurate because WebWait pulls down the entire website into your browser, so it takes into account Ajax/Javascript processing and image loading which other tools ignore. - Premasagar Rose

In this new Web 2.0, mashup world that the Internet has become, a lot of focus has been placed on the use of iframes for embedding third-party content onto a page. Iframes provide a level of security since JavaScript access it limited by domain name, so an iframe containing content from another site cannot access JavaScript on the containing page. This cross-domain restriction goes both ways as the containing page also has no programmatic access to the iframe. In all ways, the containing page and the iframed page are cut off from communication (which has led to the cross-document messaging API in HTML5). The missing piece of intrigue in most discussions surrounding iframes is JavaScript object ownership. - Premasagar Rose

"Newsreaders still feel it is worth a special and rather worrying mention if, for instance, a crime was planned by people ‘over the Internet.’ They don’t bother to mention when criminals use the telephone or the M4, or discuss their dastardly plans ‘over a cup of tea,’ though each of these was new and controversial in their day." - Premasagar Rose

ccessible data visualization in HTML has always been tricky to achieve, particularly because elements such as images allow only the most basic features for providing textual information to non-visual users. A while back, we wrote an article describing a technique we came up with to use JavaScript to scrape data from an HTML table and generate charts using the HTML 5 Canvas element. The technique is particularly useful because the data for the visualization already exists in the page in structured tabular format, making it accessible to people who browse the web with a screen reader or other assistive technology. We've now rewritten and extended the code behind this technique and packaged it up as a new jQuery plugin called "visualize", which you can download below. The plugin provides a simple method for generating bar, line, area, and pie charts from an HTML table, and allows you to configure them in a variety of ways. - Premasagar Rose
