N ot understand somethingon my code in "Use Destructuring Assignment with the Rest Parameter to Reassign Array Elements"

I solve this challenge but something in the code I did not understand some thing on my code

Is the arr variable out of the function same the arr inside the function?

My code so far


const source = [1,2,3,4,5,6,7,8,9,10];
function removeFirstTwo(list) {
"use strict";
// Only change code below this line
const [a, b, ...arr] = list; // Change this line
// Only change code above this line
return arr;
}
const arr = removeFirstTwo(source);
console.log(arr);

Link to the challenge:

arr outside of the function is a different constant reference to a value that is the same as arr inside of it.
