Compressed versions of Prototype
Written by on March 9th, 2007 in Ajax News.
John-David Dalton has spent some time compressing Prototype in a couple of ways to keep your download time to a minimum.
His package is a collection of Prototype versions 1.4, 1.5rc0, 1.5rc1, 1.5 final, and it includes original, formatted (proper semicolons, helpful for others who want to compress it), compressed, and ultraCompressed files. There is also a gzipped version of each library.
He managed to get it down to 14.4kb.
