One way to handle null or undefined values in JavaScript is by using the nullish coalescing operator. It returns the right side if the left side is either null or undefined:
const theTitle = responsesToUse[i]["Title"] ?? "Default value";
Alternatively, you can use the logical OR operator. This operator checks if the left value is falsy and then returns the right side:
const theTitle = responsesToUse[i]["Title"] || "Default value";
If you want more insights on when to use nullish coalescing versus logical OR, this question has been answered here.
title = choices[i]["Title"] ?? "";
The Logical OR operator is a useful tool:
You can use the syntax const theTitle = responsesToUse?.[i]?.["Title"] || "";
By using ?.
, you are able to verify whether the specified index
or property
exists in the source, if not, then it defaults to the value on the right side.
I hope this explanation helps clarify things for you.
