The code snippet you provided is a valid way to safely access deeply nested properties in JavaScript, using the optional chaining operator (?.) and nullish coalescing operator (??). This ensures that if any part of the chain is null or undefined, it will not throw an error and will instead return an empty string (''). Here’s a breakdown of what the code does: {{steps?.trigger?.event?.items[0]?.selectedOptions[12]?.value ?? ''}}; {{steps?.trigger?.event?.items[1]?.selectedOptions[12]?.value ?? ''}}; {{steps?.trigger?.event?.items[2]?.selectedOptions[12]?.value ?? ''}}; {{steps?.trigger?.event?.items[3]?.selectedOptions[12]?.value ?? ''}}; - steps?.trigger?.event?.items[0]?.selectedOptions[12]?.value ?? '': This attempts to access steps.trigger.event.items[0].selectedOptions[12].value. If any of these properties (steps, trigger, event, items, selectedOptions, or value) are null or undefined, it will return an empty string (''). - The same logic applies to the other lines, but for items[1], items[2], and items[3]. This approach is legal and a good practice to prevent runtime errors due to accessing properties on null or undefined objects. If you have any further questions or need additional assistance, please let me know!
