Javier Neira on 18 Nov 091. Monads aren't esoteric, abstruse computer science - they're useful. 2. You probably have used Monads but just haven't realized it. 3. jQuery is awesome.
What about the case where most products don’t have offerings, or the offerings don’t have merchants, vel cetera? If this were a frequent case, and this were inner-loop code, I might introduce a global empty object in order to reduce the object instantiation overhead (which happens right away) and the GC load (which shows up over time). E.g. define var $N={}, and use:
var product = ...,
merchantName = (((product||$N).offering||$N).merchant||$N).name;
if (merchantName)
displayMerchantName(merchantName);
