TypeScript for Data Science: A Practical Guide

The world of data analysis is traditionally associated with Python and R. But what if you know TypeScript and want to apply your skills in data science? The book "TypeScript for Data Science" is the first practical guide that proves: TypeScript can be a powerful tool for working with data, especially in web environments and when creating interactive analysis applications.

What is this book about?

The book covers the complete data workflow in TypeScript: from data acquisition and cleaning to building machine learning models and deploying them. You will learn how TypeScript's strict typing helps avoid errors when working with heterogeneous data, and how to use modern libraries for visualization and ML.

Who is this book for?

• TypeScript web developers who want to expand their skills into data analysis.
• Data scientists familiar with Python who want to try TypeScript for creating interactive dashboards and web applications.
• Students and teachers looking for an alternative approach to learning data science.
• Fullstack developers who need to integrate analytical features into existing projects.

What will you learn?

• How to efficiently work with arrays, objects, and complex data structures using TypeScript.
• Creating custom types to describe datasets and analysis results.
• Using the Danfo.js library (an analog of pandas) and TensorFlow.js for machine learning.
• Building interactive charts with Plotly.js and D3.js in TypeScript.
• Implementing algorithms: linear regression, clustering, neural networks — all in TypeScript.
• Practical examples: time series analysis, text processing, recommendation systems.
• Deploying models in the browser and on Node.js.

Why should you read it?

This book bridges the gap between web development and data science. You will learn not just to use ready-made libraries, but to understand how typing improves code quality and speeds up debugging. All examples are accompanied by real datasets and step-by-step instructions. After reading, you will be able to create full-fledged analytical applications that run faster and more reliably thanks to TypeScript.

The book is suitable both for beginners in data science (but with TypeScript experience) and for experienced analysts wanting to master a new tool. A nice bonus is ready-made project templates that can be used immediately in your work.
