javascript

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);
