Ext JS

Although I rarely develop front-end applications, let alone web applications, during my day-to-day job, I’m still practicing the skill in my personal time. Before my interests in application integration started to arise I was very much intrigued by all what is currently known as web 2.0 and Ajax. In the time we would simply call it DHTML, but that term was superseded by the more catchy ones. So if I see someting passing by that really looks cool and is built using simply Javascript and HTML I always take a quick look at it.
