35612-35620: Consider refactoring to reduce nesting and improve readabilityWhile the logic is correct, the code could be more maintainable with early returns and clearer variable names.
Here's a suggested refactor:
- var chn = DeviceList.getChannelByAddress(channelAddress); - if (typeof chn != "undefined") { - var chnMode = parseInt(chn.multiMode); - if (! isNaN(chnMode)) { - typeExt = "_" + chnMode; - } else { - typeExt = ""; - } - } + const channel = DeviceList.getChannelByAddress(channelAddress); + if (typeof channel === "undefined") { + typeExt = ""; + return; + } + + const channelMode = parseInt(channel.multiMode); + typeExt = !isNaN(channelMode) ? `_${channelMode}` : "";Changes made:
- More descriptive variable names
- Early return to reduce nesting
- Use of template literals for string interpolation
- Use of const for immutable variables

Line range hint
1-13: LGTM! Improved control flow efficiency.The reordering of checks is a good optimization. Checking
channelTypefirst is more efficient as it avoids unnecessary channel lookups when the type is directly available.Consider adding a comment explaining the order preference to help future maintainers understand the optimization:
+ // Check channelType first for efficiency, fall back to channelAddress lookup if needed if (typeof channelType != "undefined") {
30-37: Fix indentation for better readability.The indentation of the new code block appears inconsistent with the surrounding code.
Apply this formatting fix:
if (typeof chn != "undefined") { - var chnMode = parseInt(chn.multiMode); - if (! isNaN(chnMode)) { - typeExt = "_" + chnMode; - } else { - typeExt = ""; - } + var chnMode = parseInt(chn.multiMode); + if (! isNaN(chnMode)) { + typeExt = "_" + chnMode; + } else { + typeExt = ""; + } }

35612-35614: LGTM! Good addition of null check
The addition of the null check for chn before accessing its properties prevents potential runtime errors, which directly addresses the issue mentioned in the PR objectives.

26-40: Good catch! Fixed potential undefined object access.
The addition of the typeof chn != "undefined" check prevents runtime errors that could occur when trying to access properties of an undefined channel object. This directly addresses the issue mentioned in the PR objectives.
26-40: Verify handling of all channel description scenarios.
While the fix looks good, please ensure testing covers these scenarios:
- Channel exists with valid multiMode
- Channel exists with invalid multiMode
- Channel doesn't exist
- Channel address is undefined
