Hello!
I want to find duplicates in array below and put them into a new array. No sorting.
Array:
apple, plum, banana, apple, plum, orange, apple, apricot, strawberry
Result array:
apple, plum
or
plum, apple
How to do it in a simple way?
Hey @garry
You can create a set variable module and put all elements, after that you use iterator to iterate the proces.
create two arrays - seen and duplicate (keep them empty initially). Using filters saturate the elements and check if the element exists or not.
Not really understand your idea.
By the way I have several arrays with duplicates and should create copies of them with duplicates only.
Welcome to the Make community!
All you need is to “filter” the grouped arrays that has more than one item:

Module Export
You can copy and paste this module export into your scenario. This will paste the modules shown in my screenshots above.
-
Copy the JSON code below by clicking the copy button when you mouseover the top-right of the code block
-
Enter your scenario editor. Press ESC to close any dialogs. Press CTRLV (paste keyboard shortcut for Windows) to paste directly in the canvas.
-
Click on each imported module and save it for validation. You may be prompted to remap some variables and connections.

You selected the wrong array variable.
Copy and paste my module export.
