Overview of the Repository
This repository provides JavaScript implementations of many popular algorithms and data structures. Each section includes detailed explanations, links to further reading, and video resources to facilitate learning.
Data Structures
Data structures are essential for organizing and storing data efficiently. Here are some key data structures included in the repository:
- Linked List: A linear collection of elements where each element points to the next.
- Doubly Linked List: Similar to a linked list but with links to both the next and previous elements.
- Queue: A collection that follows the First In, First Out (FIFO) principle.
- Stack: A collection that follows the Last In, First Out (LIFO) principle.
- Hash Table: A structure that maps keys to values for efficient data retrieval.
- Graph: A collection of nodes connected by edges, used to represent relationships.
Algorithms
Algorithms are step-by-step procedures for calculations. The repository covers a wide range of algorithms, organized by topic:
- Sorting Algorithms: Includes Bubble Sort, Merge Sort, and Quicksort.
- Search Algorithms: Features Linear Search and Binary Search.
- Graph Algorithms: Such as Dijkstra's and Kruskal's algorithms for pathfinding.

Code Examples
Example: Implementing a Stack
class Stack {
constructor() {
this.items = [];
}
push(element) {
this.items.push(element);
}
pop() {
if (this.isEmpty()) return null;
return this.items.pop();
}
isEmpty() {
return this.items.length === 0;
}
peek() {
return this.items[this.items.length - 1];
}
}
Example: Implementing Quick Sort
function quickSort(arr) {
if (arr.length <= 1) return arr;
const pivot = arr[arr.length - 1];
const left = [];
const right = [];
for (let i = 0; i < arr.length - 1; i++) {
if (arr[i] < pivot) left.push(arr[i]);
else right.push(arr[i]);
}
return [...quickSort(left), pivot, ...quickSort(right)];
}
