When to use call and apply

A very common interesting question for Javascript engineers. What is the difference between call and apply?

Call and Apply provide you a way to work with the arguments as array objects. Just remember that Apply accepts two arguments but Call can take an unlimited number.

function applyArray(){ return Array.prototype.pop.apply(arguments); }; applyArray('jump','run','hike'); // hike 

Working in statements and expressions require us to use the this Javascript object. Using the call and apply functions allow us to route and reconfigure default javascript behaviors.

Publishing Video on the Web

Video and images. Broadband internet usage is growing rapidly. More video is being published on the web everyday. Many vendors have turned to Google's YouTube to syndicate their content. Today YouTube can essentially serve as a CDN, providing you with a well documented API to create Chromeless players and the like. In this manner, the video is served from a cloud of network servers located within a proximal distance from the original request. Images download faster and videos play smoother. For quite a while now, we have been coming up with new ways to serve up our data faster. Despite our high-powered file servers and hardware, we are unable to cater to the world wide web. Content Delivery Networks are needed for videos to stream smoothly and images to show immediately.
