Raul, your library sounds interesting. Please share more if you can later. Coffeescript is a fun language. The lambda syntax and lack of braces make it feel closer to the problem domain than native javascript. It also makes it harder to shoot yourself in the foot. The debugging and compilation has greatly improved over the years too. The compiler throws useful errors with line numbers etc.
I agree that toys are useful for learning. It's common in the land of lisp to write a toy interpreter to better understand the language. I did that too and found putting this one together a nice break On Thu, Jan 23, 2014 at 12:12 PM, Raul Miller <[email protected]> wrote: > I've been building an vsapl-like javascript library.
