I arrived here after a short lesson on Solidity and came across the map function. After several watches on mapping, this is the one that finally made it crystal clear. I loved the way you explained it and set the function up to be called in the actual array map. So much neater and tidier. Thank you once again sir.

You think and explain more similarly to me than others at freeCodeCamp, videos, and articles. You add a style of explaining. Thank you.

Obj is a array of objects, confused me there for a second because I thought you were returning an object. I'm clear, it was just the name not the type.
