Function clean() at line number 17 in post.js, function set() at line number 98 in util.js and function visibility() at line number 2767 in media-views.js can be improved with same functionality.

I measured inclusive execution times of original code and improved code. The image is the result. The machine I used to measure execution times has Intel Core i5 1.6GHz CPU and 4GB RAM. 

I also attached a patch file.",enhancement,new,normal,Awaiting Review,Performance,3.5,normal,,has-patch,
