Rest/Spread operator

Both are used with ...

Spread operator:

spread operator help to expand elements out from array or object

It converts array into list of items (it means it copy the array element)

Rest operator:

rest operator helps to gather all remaining arguments into an array.

It is always written in last argument where ever it is used.
