DSA with JavaScript

Data Structures and Algorithms (DSA) with JavaScript involves a structured approach. Here's a detailed roadmap to help you navigate through the key concepts and techniques:

1. Foundations

JavaScript Basics:

• Understand variables, data types, operators, and control structures (if-else, loops).
• Functions, scope, and closures.
• ES6+ features: let/const, arrow functions, template literals, destructuring, spread/rest operators.

Basic Data Structures:

• Arrays and Strings.
• Objects and Maps.

2. Core Data Structures

Linear Data Structures:

• Arrays: Basic operations, multi-dimensional arrays.
• Linked Lists: Singly, doubly, and circular linked lists.
• Stacks: LIFO principle, stack operations.
• Queues: FIFO principle, circular queue, priority queue.

Non-Linear Data Structures:

• Trees: Binary trees, binary search trees (BST), AVL trees, red-black trees.
• Heaps: Min-heap, max-heap.
• Graphs: Representations (adjacency list, adjacency matrix), types of graphs (directed, undirected, weighted, unweighted).

3. Advanced Data Structures

Hashing:

• Hash tables, hash functions, collision resolution techniques (chaining, open addressing).

Trie:

• Prefix trees for efficient string operations.

4. Algorithms

Sorting Algorithms:

• Bubble sort, selection sort, insertion sort.
• Merge sort, quicksort, heap sort.
• Counting sort, radix sort, bucket sort.

Searching Algorithms:

• Linear search, binary search.
• Search in rotated sorted array.

Dynamic Programming:

• Concepts of memoization and tabulation.
• Classic problems: Fibonacci sequence, knapsack problem, longest common subsequence.

Greedy Algorithms:

• Activity selection, coin change problem, Huffman coding.

Graph Algorithms:

• Depth First Search (DFS), Breadth First Search (BFS).
• Shortest path algorithms: Dijkstra’s, Bellman-Ford.
• Minimum spanning tree algorithms: Kruskal’s, Prim’s.

Backtracking:

• N-queens problem, subset sum, permutation and combination generation.

Here’s a proposed directory structure and a flow chart for organizing DSA (Data Structures and Algorithms) content using JavaScript. This structure is suitable for a teaching project or a self-learning resource.
