Concat 2 list, with data dedupped (duplicated data get removed).
Basically it concats 2 list, but if any data in list2 having the same id as
one in list1, the one on list1 will be replaced by the one in list2.
For example:
list1 = [ A, B, C ]
list2 = [ C', D, E] // C' is the modified version of C
concat(list1, list2) --> [A, B, C', D, E]
An important note that it's a concat rather than merge, the order in list1 remains the same
For example:
list1 = [ B, C, D ]
list2 = [ A, B, C', D, E ]
concat(list1, list2) --> [B, C', D, A, E]
Items from list1 [ B, C, D ] remains the same, but with C updated
Non-duplicated items [A, E] from list2 are appended
