ClojureScript vs. CoffeeScript for Processing sketches
DECEMBER 2015 UPDATE: I’ve run some tests with the latest ClojureScript and made some minor changes to the code, which significantly improved performance. Read this post for updated numbers. Keeping this post around for archival reasons.
The set up
This whole thing started not as a performance test, but as me experimenting with ClojureScript and Quil while reading Matt Pearson’s Generative Art. As such, it is not the most scientific of comparisons, and instead born out of my notes when exploring how to do sketches with ClojureScript for the web.
Consider the following example:
CoffeeScript
CoffeeScript is a huge improvement, but underneath all that synctactic sugar it’s clearly still Javascript:
