flatten

flatten - flattens a nested array.

DESCRIPTION

This utility takes a nested, multi-dimensional array and returns a new, flattened array. The second argument to flatten can be given as an integer and it will determine the depth by which to flatten the array. This argument is optional and it defaults to Infinity i.e. the array will be flattened down to one dimension.

SYNOPSIS

flatten(ARR, [DEPTH])

PARAMETERS:

• ARR Array to flatten.
• DEPTH If integer is specified, the array will be flattened only by the given depth. This argument is optional and it defaults to Infinity (i.e. flattens the array to one dimension).

RETURN VALUE: New, flattened, array; original array is left unchanged.
