@thi.ng/dcons

Comprehensive doubly linked list structure with:

• ES6 iterator support
• Stack & queue API (front and/or back)
• Random node access (read / write, O(n/2))
• Node insertion (also w/ custom comparator)
• Node finding (O(n))
• Node swaps (O(1))
• Reversing (O(n/2))
• Rotation (left / right) (O(1))
• Shuffling
• Slicing (sublist copies)
• Splicing (delete and/or insert)
• release() (emptying, GC friendly)
• concat() / into()
• map() / filter() / reduce()
• compare() / equiv()
• toJSON() transform (-> array)
