Algorithms and Data Structures in TypeScript

This book is a practical guide to fundamental algorithms and data structures implemented in TypeScript. Whether you write frontend in React, backend in Node.js, or mobile applications, a deep understanding of algorithms is the key to writing efficient and scalable code.

Who is this book for?

• Beginner developers who want to build a solid foundation in Computer Science.
• Experienced JavaScript/TypeScript programmers seeking to systematize their knowledge.
• Anyone preparing for technical interviews at IT companies.

What you will learn:

• Basics of complexity analysis: Learn to evaluate algorithm performance using Big O notation and choose optimal solutions.
• Linear structures: Arrays, linked lists, stacks, and queues — their implementation and application in real projects.
• Trees and graphs: Binary search trees, AVL trees, BFS, DFS, Dijkstra's and A* algorithms.
• Sorting algorithms: From bubble sort to Quicksort and Merge Sort with performance analysis.
• Hash tables and sets: Efficient data storage and retrieval.
• Dynamic programming: Solving complex problems by breaking them into subproblems (knapsack problem, longest common subsequence).
• TypeScript specifics: Using strict typing, generics, and interfaces to create robust and reusable structures.

Features of the edition:

• Each algorithm comes with ready-to-use TypeScript code with explanations.
• Over 50 practical problems with solutions to reinforce the material.
• Visual diagrams and complexity tables for clarity.
• Chapters are structured from simple to complex — can be read sequentially or used as a reference.

This book will be your guide in the world of algorithms. You will stop fearing complex terms and learn to use data structures as naturally as loops and conditionals. After reading it, you will be able to confidently pass interviews, optimize existing code, and design architecture that can handle any load.

Dive into the world of efficient programming with TypeScript — a language that combines the flexibility of JavaScript with the reliability of static typing.
