Possible to ignore Cannot read property '0' of undefined? [duplicate]

Answer 1

Even if you can use try and catch I wouldn't do that, I prefer avoid errors at all, so you'd just need to check the object you're reading:

if(item && item["OfferSummary"].length && item["OfferSummary"][0]["LowestUsedPrice"].length) {
   //then do whatever
}

if you know that item is always defined you can avoid to check it in the if.
