Today, I will explain how to unique an array of object by property
filter
for SimplicityAlternatively, you can use the filter
method for uniqueness by checking if an item's index matches its first occurrence:ExplanationMap and Set: Efficient for large arrays because they use hashing for uniqueness.
filter + findIndex: More readable but can be slower for large arrays due to nested iterations.
Custom Combination Key: Use when uniqueness depends on multiple properties.
