Question

Creates a new sequence with every element from this sequence, and with arrays exploded so that a sequence of arrays (of arrays) becomes a flat sequence of values.

Signature

Sequence.flatten = function(shallow) { /*...*/ }

Sequence.flatten = function flatten(shallow) {
  return new FlattenedSequence(this, shallow);
}

Name	Type(s)	Description
shallow	boolean	Option to flatten only one level deep (default is recursive).
returns	Sequence	The new sequence.

Examples

Lazy([1, [2, 3], [4, [5]]]).flatten()     // sequence: [1, 2, 3, 4, 5]
Lazy([1, [2, 3], [4, [5]]]).flatten(true) // sequence: [1, 2, 3, 4, [5]]
Lazy([1, Lazy([2, 3])]).flatten()         // sequence: [1, 2, 3]
