What do the instructions tell you to do with that number?

i have to add it at the end of the array and remove the first one. I tried that with push(item) didn’t work. i feel like i am missing some basics of basics

What was the exact line of code you tried with push(item) because that is not what you wrote above? Above you pushed just the number 10 to arr.

That use of push was correct. It is the next line that is not correct. It is close, but is missing something. You should research what value the shift method returns and then make use of it.
