Rest ...arrays: any[][]one array
Given a list of arrays which contain holes, this method will splice all arrays together into one, maintaining indices, filling holes where indices exist. This is intended for the specific case where all arrays originally came from a single array, such as in the subgraph() method, this method will re-join these arrays. In the case where some arrays double up on indices, the index will be overwritten, by the last array parameter in the sequence.
arrays containing any type.
