Slice the array for certain value and keep the stuff that you “didnt” slice

This is more of a constructive question, i am trying to slice one array, but store the stuff that i didnt slice in new array. The logic would be like ['a','b','c','d'], and i would be left with ['a','b','c'], but what happens to ['d']? I would want to keep that value, as this will be for like payment icons, have a limit to show only 5, and have load more button
