js-sdsl

What is js-sdsl?

The js-sdsl package is a JavaScript library that provides a variety of data structures and algorithms. It is designed to be efficient and easy to use, offering structures like vectors, lists, queues, stacks, and trees, as well as algorithms for sorting, searching, and other operations.

What are js-sdsl's main functionalities?

Vector

Vector is a dynamic array that can grow and shrink in size. It provides random access to elements, similar to an array.

const { Vector } = require('js-sdsl');
let vector = new Vector();
vector.pushBack(1);
vector.pushBack(2);
console.log(vector.size()); // Output: 2

LinkedList

LinkedList is a sequence of elements where each element points to the next. It allows for efficient insertion and removal of elements from any position.

const { LinkedList } = require('js-sdsl');
let linkedList = new LinkedList();
linkedList.pushBack(1);
linkedList.pushFront(0);
console.log(linkedList.front()); // Output: 0

Queue

Queue is a first-in-first-out (FIFO) data structure that allows for efficient addition of elements at the end and removal from the front.

const { Queue } = require('js-sdsl');
let queue = new Queue();
queue.push(1);
queue.push(2);
console.log(queue.front()); // Output: 1

Stack

Stack is a last-in-first-out (LIFO) data structure that allows for adding and removing elements from the top of the stack.

const { Stack } = require('js-sdsl');
let stack = new Stack();
stack.push(1);
stack.push(2);
console.log(stack.top()); // Output: 2

Tree

Tree structures like AVLTree are used to store data in a hierarchical manner. AVLTree is a self-balancing binary search tree.

const { AVLTree } = require('js-sdsl');
let tree = new AVLTree();
tree.insert(1);
tree.insert(2);
console.log(tree.find(1)); // Output: true

Other packages similar to js-sdsl

immutable

Immutable.js offers persistent immutable data structures. Unlike js-sdsl, which provides mutable structures, Immutable.js ensures that the data cannot be changed once created.

lodash

Lodash is a utility library that provides functions for common programming tasks, including manipulating and testing values, arrays, objects, and strings. It is more focused on utility functions than the data structure implementations provided by js-sdsl.

underscore

Underscore.js is a utility library similar to Lodash, offering a range of functions for working with JavaScript collections and arrays. It does not focus on providing data structures but offers many utilities for working with existing ones.
