Don't call parseMedia in the media loop #6

Closed tvler closed 8 years ago

tvler commented 8 years ago

Looks like

for (var i = 0; i < (media = parseMedia(media)).length; i++)

runs the parseMedia function for every loop iteration. I thought that it would just be called once for the variable setup.

This is pretty bad for performance, will fix.
