[⚠️correctness]
Using the nullish coalescing operator (??) to defaultaiReviewers to an empty array is a good practice. However, ensure that the rest of the codebase correctly handles an empty array foraiReviewers to avoid unintended behavior.

[💡maintainability]
The conditional checkcolumn.label && { ... } can lead to a potential issue whereundefined is included in the array, which is then filtered out. Consider restructuring this logic to avoid addingundefined in the first place, which can improve readability and maintainability.

[⚠️correctness]
Using the nullish coalescing operator (??) to defaultprops.aiReviewers to an empty array is a good practice for avoidingundefined values. However, ensure that the rest of the codebase is prepared to handle an empty array as a valid input, as this might change the behavior if previouslyundefined was expected to be handled differently.

[⚠️correctness]
The use ofcolumn.label && in the map function could lead to unexpected behavior ifcolumn.label is falsy but notundefined ornull. Consider explicitly checking forundefined ornull if those are the only cases you want to handle.

[⚠️performance]
TheuseMemo hook is used to memoize theaiReviewersColumn even whenprops.aiReviewers is undefined or empty. This could lead to unnecessary computations and memory usage. Consider adding a condition to returnundefined whenprops.aiReviewers is not present or empty.

[💡performance]
The use ofcolumn.label && in the map function could lead to afalse value being pushed into the array, which is then filtered out. This pattern is not optimal. Consider using a conditional (ternary) operator to directly return the object ornull to avoid unnecessary filtering.

[❗❗correctness]
Using non-null assertion (!) onprops.aiReviewers could lead to runtime errors ifaiReviewers isundefined. Consider adding a check or providing a default value to ensure safety.

[❗❗correctness]
The expression!allRows.indexOf(data) will always evaluate tofalse becauseindexOf returns-1 for non-existent elements, which negates totrue. Consider usingallRows.indexOf(data) === -1 to check for non-existence.
