Calculate the date yesterday in JavaScript
... If you need a one-liner, use something like new Date( Date.now() - 24*60*60*1000 ); this has the benefit of only creating one Date object. But honestly, whoever's maintaining this code will be much happier to see the clear 2-line version than they would something throwing functions ...
