About the Book
JavaScript is one of the most powerful programming languages in the world, but learning it properly can be overwhelming. This book was written to solve that problem.
Code to Career takes you from absolute beginner to professional JavaScript and Node.js development through a carefully structured learning path. Instead of only explaining syntax, it focuses on understanding how modern JavaScript works in real-world applications.
Inside this book you'll learn:
• Modern JavaScript (ES6+)
• Asynchronous programming
• Node.js from the ground up
• REST APIs
• Express.js
• Authentication & Authorization
• SQL & PostgreSQL
• File systems and streams
• Performance optimization
• Security best practices
• Testing
• Deployment
• Interview preparation
• Career roadmap
With more than 1,100 pages, hundreds of examples, diagrams, quizzes, exercises, and practical projects, this book is designed to help you build real skills instead of simply memorizing syntax.
Whether you're starting your programming journey or preparing for your first software engineering job, this book provides a complete roadmap from writing your first line of JavaScript to building production-ready backend applications.

About the Author
Mert Turedu
Hi, I’m Mert Turedu, a software engineer passionate about building products and helping developers grow beyond tutorials.
Over the past several years, I’ve worked on production mobile applications, AI-powered products, backend services, and large-scale software systems. Throughout my career, I’ve had the opportunity to design applications used by millions of users, optimize performance, build scalable architectures, and work with modern technologies across the full software development lifecycle.
While working with developers at different experience levels, I noticed a common pattern: many resources teach syntax, but very few explain how experienced engineers actually think when solving real-world problems. That gap inspired me to write this book.
Code to Career: JavaScript & Node.js from Zero to Professional is the result of countless hours of development, research, writing, and practical experience. Rather than being a collection of isolated tutorials, it is designed as a complete learning journey that gradually builds both programming knowledge and engineering mindset.
Inside this book you’ll find not only JavaScript and Node.js fundamentals, but also object-oriented programming, asynchronous programming, backend development, REST APIs, databases, authentication, security, software architecture, testing, deployment, debugging strategies, interview preparation, and real-world projects that reflect how modern software is actually built.
My goal has always been simple: to create the resource I wish I had when I first started programming. A book that explains not only how to write code, but also why experienced engineers make certain decisions, how systems evolve over time, and how to transition from learning syntax to thinking like a professional software engineer.
Whether you’re writing your first lines of JavaScript or preparing for your first software engineering role, I hope this book becomes a trusted companion throughout your journey.
Thank you for reading, and welcome to the world of software engineering.
