Overview of this book

Julia is a new programming language that offers a unique combination of performance and productivity. Its powerful features, friendly syntax, and speed are attracting a growing number of adopters from Python, R, and Matlab, effectively raising the bar for modern general and scientific computing. After six years in the making, Julia has reached version 1.0. Now is the perfect time to learn it, due to its large-scale adoption across a wide range of domains, including fintech, biotech, education, and AI. Beginning with an introduction to the language, Julia Programming Projects goes on to illustrate how to analyze the Iris dataset using DataFrames. You will explore functions and the type system, methods, and multiple dispatch while building a web scraper and a web app. Next, you'll delve into machine learning, where you'll build a books recommender system. You will also see how to apply unsupervised machine learning to perform clustering on the San Francisco business database. After metaprogramming, the final chapters will discuss dates and time, time series analysis, visualization, and forecasting. We'll close with package development, documenting, testing and benchmarking. By the end of the book, you will have gained the practical knowledge to build real-world applications in Julia.

Creating a new Julia package

In order to create a new package, we must first satisfy a few prerequisites. To start with, we need git installed and configured on the development machine. The obvious reason for this is that, by default, Julia uses git and GitHub ( to host packages (although third-party, including private package, registries can also be used). If your current choice of operating system does not come with git preinstalled, please visit for the official download page. Pick the right version for your OS and follow the installation instructions.

Second, if you don't already have a GitHub account, you'll need one. Please visit and set up a free account.

Now that we have git installed and a GitHub account, let's set up some global configuration options, as they'll come in handy. Open a new Terminal window and execute the following—please make sure to replace the placeholder text within <...> with your actual...
