What are you returning? What logic do you have in there? In other words, what are you doing to get the right answer? All I see is that you are looping and logging out some data.

am just trying to see if source is inside collection so i can then push it to arr and return the answer

#4

What type of thing is source? What types of arguments does hasOwnProperty use? Do those two types agree?

ok if i understand hasOwnProperty correctly i should be able to compare 2 objects with it thats why am trying to loop inside collection and see if source is inside it (am i thinking correctly ?)

#6

Parameters
prop
The String name or Symbol of the property to test.

#7

i see that means i should transform source to a string and then compare it using Object.entries(source) thats correct ?

#8

Not quite. The challenge wants you to check all objects in the array collection and find all that have every property of source and that property set to the same value.
