Remove duplicate JSON records in JavaScript by comparing and filtering based on identical attributes

Looking to remove duplicates from a JSON object

[{id:1,name:a, cat:1},{id:1, name:a, cat:2},{id:2, name:b, cat:8}] 

I want to keep only the first occurrence of each duplicated id

[{id:1,name:a, cat:1},{id:2, name:b, cat:8}]

Answer №1

One possible solution could involve creating a loop and a separate array to store unique names. By iterating through each item, you can check if its name is already present in the new array. If not, add it to a distinct object for unique values and also include it in the new array for future comparisons.

I won't provide the exact code for you, as it's a good opportunity for you to try implementing it on your own now that you have a clear idea of the approach. Good luck! :)
