JavaScript Data Structures
The JavaScript data structures collection includes implementations and examples of some of the most commonly-used data structures. Data structure snippets are best used as a learning resource, as they might require optimizations to run in production.
Native JavaScript Data Structures
JavaScript, Object
JavaScript provides a handful of native data structures that you can start using in your code right now.
JavaScript Data Structures - Queue
JavaScript, Object
A queue is a linear data structure which follows a first in, first out (FIFO) order of operations.
JavaScript Data Structures - Stack
JavaScript, Object
A stack is a linear data structure which follows a last in, first out (LIFO) order of operations.
JavaScript Data Structures - Linked List
JavaScript, Object
A linked list is a linear data structure where each element points to the next.
JavaScript Data Structures - Doubly Linked List
JavaScript, Object
A doubly linked list is a linear data structure where each element points both to the next and the previous one.
JavaScript Data Structures - Graph
JavaScript, Object
A graph is a data structure consisting of a set of vertices connected by a set of edges.
JavaScript Data Structures - Tree
JavaScript, Object
A tree is a data structure consisting of a set of linked nodes representing a hierarchical tree structure.
JavaScript Data Structures - Binary Tree
JavaScript, Object
A binary tree is a data structure consisting of a set of linked nodes representing a hierarchical tree structure, in which each node can have at most two children.
JavaScript Data Structures - Binary Search Tree
JavaScript, Object
A binary search tree is a data structure consisting of a set of ordered linked nodes representing a hierarchical tree structure, in which each node can have at most two children.
Frequency Map Data Structure
JavaScript, Object
A custom data structure to keep track of value frequencies in an array.
