Code is the new literacy.

Six hundred years ago, most people couldn't read. In 1440, the invention of the printing press laid the groundwork for massive increases in literacy and ushered in the modern era.

Today, computers and the internet are causing a similar tectonic shift. Reading and writing are foundational skills, and in our digital world, coding is too.

But coding can be intimidating to learn. What is code? Where do you even start?

In Read Write Code, Jeremy Keeshin demystifies the world of computers, starting at the beginning to explain the basic building blocks of today's tech: programming, the internet, data, apps, the cloud, cybersecurity, algorithms, artificial intelligence, and more.

As CEO and Co-founder of CodeHS, Keeshin has helped teach coding to millions of students over the last decade. Complex concepts are explained in friendly and engaging ways, with interactive examples and practical tips. This book is a must-read for modern educators and anyone who wants to understand why code matters today.
