GWT (Google Web Toolkit) should be familiar to many people, and the power of ExtJs is something that a lot of web developers have probably experienced firsthand. So, what would happen if we combined these two? Through Dreamer's article, I learned that someone has actually integrated these two, and thus the extremely powerful widget library called gwt-ext was born. Its performance can only be described as "stunning," which is the same feeling I had after experiencing Fjax.
