I remember about 3-4 years ago, a couple of programmers talking. One said to the other, "you know, javascript is getting respectable now." I'm blown away by how such a complicated system can be described and implemented in so few lines of code. When I went to school, seriously complicated programs took a lot of time to write and render. The easy way involved Matlab because it had a lot of graphics libraries. It looks like javascript really has turned the corner into becoming a language with serious possibilities.
