Julia for Data Science (Video 9)

This video tutorial explores the concept of macros in Julia, highlighting their importance in creating concise and efficient code. It covers the mechanics of macros, including expressions and evaluation, and provides examples of using built-in macros like @time and @print. The tutorial also guides viewers through creating custom macros such as 'timeit' and 'repeat', and discusses debugging techniques. Additionally, it introduces some useful built-in macros for testing and system-specific operations.
