-Variables `a` and `b` take the first and second values from the array. After that, because of the rest parameter's presence, `arr` gets the rest of the values in the form of an array. The rest element only works correctly as the last variable in the list. As in, you cannot use the rest parameter to catch a subarray that leaves out the last element of the original array.
