Julia for Beginners : From Romans to Rockets

earn the hot new programming language for Data Science and Machine Learning. Julia is an easy to use, high performance, general programming language. You can use Julia for anything from simple scripting to writing a climate model running on a super computer. 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. The important reason I wanted to write this book is because people keep telling me: “Julia? Isn’t that a language only for science and scientists?” Julia has had major success in this area, which is why the Julia community today is full of brainy people working on hard problems such as developing new drugs, modeling the spread of infectious diseases, climate change or the economy. But no, you don’t need to be a genius or a scientists to use Julia. Julia is a wonderful general purpose programming language for everyone! I am not a scientist and I have enjoyed using it for over 7 years now. With Julia you will find that you can solve problems more quickly and elegantly than you have done in the past. And as a cherry on top, computationally intensive code will run blisteringly fast.
