what parts are confusiong you?
what is it that you don’t understand?

Okie I guess I took a bit too serious about myself as a 9yr old and didn’t specify my confusion part


Well, let’s start with what I think I am able to understand. So far I can see there is an object with a name recordCollection and it has 4 elements in it. And we are creating a function with 4 parameters. Records = object/“recordCollection”, id = 2548/2468 
, prop = artist/tracks
, value = whatever the value we want to input or change is it right so far?

I get issues with creating the function part, the logical part. Even though I read the question I just get confused with building this stuff
 You know what I mean? How does function understand when I say records, id, prop and value. How does the function know that “records” mean fetch info from “recordCollection” or “Id” means "2458 " so on
 and are there any limitations of arguments in function? or we can put as many according to the object or arrays? I think all these things are easy it’s just not clicking in my head yet :sweat_smile:

btw how’s your washing machine? did you able to fix it haha 


Thanks

P.S don’t worry im, not a stalker just a curious person.

When the function is called, certain arguments are passed in, and these arguments become

You need to take the object that is passed in as records and update it based upon the id, prop, and value provided.
