Julia

Learn the awesome Julia programming language by building fun projects like a rocket launcher, a password keeper, and a battle simulator.

Julia as a Second Language covers:

• Data types like numbers, strings, arrays, and dictionaries
• Immediate feedback with Julia’s read-evaluate-print-loop (REPL)
• Simplify code interactions with multiple dispatch
• Sharing code using modules and packages
• Object-oriented and functional programming styles

Julia as a Second Language introduces Julia to readers with a beginning-level knowledge of another language like Python or JavaScript. You’ll learn by coding engaging hands-on projects that encourage you to apply what you’re learning immediately. Don’t be put off by Julia’s reputation as a scientific programming language—there’s no data science or numerical computing knowledge required. You can get started with what you learned in high school math classes.

The Julia programming language is acclaimed in scientific circles for its unparalleled ease, interactivity, and speed. Practical Julia is a comprehensive introduction to the language, making it accessible even if you’re new to programming.

Dive in with a thorough guide to Julia’s syntax, data types, and best practices, then transition to craft solutions for challenges in physics, statistics, biology, mathematics, scientific machine learning, and more. Whether you’re solving computational problems, visualizing data, writing simulations, or developing specialized tools, Practical Julia will show you how.

As you work through the book, you’ll:

• Use comprehensions and generators, higher-level functions, array initialization and manipulation, and perform operations on Unicode text
• Create new syntax and generate code with metaprogramming and macros, and control the error system to manipulate program execution
• Visualize everything from mathematical constructs and experimental designs to algorithm flowcharts
• Elevate performance using Julia’s unique type system with multiple dispatch
• Delve into scientific packages tailored for diverse fields like fluid dynamics, agent-based modeling, and image processing

Whether your interest is in scientific research, statistics, mathematics, or just the fun of programming with Julia, Practical Julia will have you writing high-performance code that can do real work in no time.
