Ways Of Writing Javascript

The way developers write javascript code has changed enormously over the years.

Here are the pros & cons of the three options in the way you can write javascript these days.

1. Hand code everything:
   
   • Write all javascript code from scratch.
   • Deal directly with browser compatibility issues.
   • Very flexible (upto the point, you can decide on the name of your temporary variable ;) ).


2. Use Generic Utilities:
   You get/download the generic javascript utilities written by others (friends, fellow developers), & with little customization use them in your applications.
   
   • Saves some time to get things working.
   • Browser compatibility issues may be taken care by the generic utilities
   • You should deal with the customization errors
   • Flexible, until you are faced with a bug/error which was not faced by the person who created the utility. (Could be because your application required slightly different behavior)


3. Use Javascript Toolkits/Frameworks:
   Use the popular javascript toolkits available on internet (for free). Some of the widely used toolkits are jQuery, prototype, YUI, dojo, etc.,
   
   • Download & use directly in your applications. As simple as including a js file & start using all the wide range of features provided.
   • Little/No javascript experience required.
   • Provides ready to use UI widgets. (like Plug & Play)
   • Provides AJAX facilities
   • Browser compatibility is no more an issue. All toolkits takes care of these internally.
   • Flexibility is less: If you want to change anything for your taste, understanding & changing the core code is time consuming.
   • Most of these toolkits provide a way for developer to extend & create your own widgets

As we can see, using javascript toolkits is the best option.

In my next article, we'll look into each of these toolkits & compare them.
