Ajax Web Workers

JavaScript is not the only programming language that’s making strides in order to offer better user experience. Other programming language and tools are aggressively improving not to keep up with JavaScript but basically to cater to the needs of users worldwide.

Although there are legacy codes that will last for ages, some things have to be added or tweaked slightly to improve its performance. JavaScript is probably the best example for programming language development because of the aggressive input from developers as they create more APIs, Libraries and applications that would improve user experience.

One of those languages that constantly improve is HTML 5. This form of programming language is special for JavaScript since it offers improvements of HTML while catering to the demands of JavaScript. Even though it’s still on its early stage, HTML 5 shows a promising future for JavaScript.

The reason for its promising improvement is the creation of Web Workers. This tool is an offshoot of HTML 5 which became an independent entity simply because it has become an important tool for JavaScript and other client side programming languages. This is actually a good thing as focus was made to Web Workers which resulted to significant improvement for client side programming languages.

A web worker is basically an API that could be implemented in various applications. Its main role is to provide additional processing power to client side programming. The user will be able to enjoy more interaction since the application will be able to run with the user request while some processes are done on the background. Web Workers basically enable background processing for client side applications.

This feature offers a significant advantage for JavaScript developers. Loading time will be faster with the help of a Web Worker. The application can instantly interact with the user while the rest of the functions that will be used later will be loaded in the background.

But Web Workers are never the perfect answer to processing problems. Developers should avoid or better yet, never implement two Web Workers in a single online application. A web worker will require a lot of resources from the online application that two web workers will most likely stop the application from processing further.

It’s a very heavy load for the client side application. JavaScript is already using a lot of processing power from the browser. One Web Worker will be able to work well with JavaScript applications but the browser will take its toll when two or more Web Workers are used.

But even with this disadvantage, Web Workers are highly recommended for JavaScript applications. Although Web Workers are still on its early stages of development, some implementations have shown significant improvement with the help of Web Workers.

Last but not the least; Web Workers are implemented as APIs. This means, developers could create custom Web Workers and implement them in various online applications if they see the coding can accept a Web Worker API. Portability, efficiency of an application with heavy processing requirement can be expected from Web Workers.
