This page compares JavaScript minifiers for various inputs across various settings.
Note: the input programs are not comparable against one another because they do wildly different things. Don't compare "angularjs" against "react", but rather for a given input program compare the different minifiers (uglify vs closure etc.).
See the README for more background on the methodology. Click on rows/columns of the results to see their definitions.
Note: many of these are marked 'untested'. See the discussion in the README of why you should treat those results with suspicion.
