Julia for Beginners

From Romans to Rockets

About the Book

A beginner-friendly guide to the Julia programming language. Julia is an exciting, young programming language rapidly gaining popularity in the areas of Data Science, Machine Learning and High-Performance Computing.

While Julia is exceptionally good in these areas, we believe Julia is also an exceptionally powerful general purpose programming language and believe there should be a book teaching Julia to beginners or experienced developers alike.

This book engages the reader with fun programming examples involving building and launching a rocket, implementing simple encryption algorithms used by Roman armies, and simulating a mechanical calculator. While the book aims to be beginner friendly, we don’t shy away from the important detail of how multiple dispatch works, or how to think about functional and object-oriented programming in Julia.
