Julia 1.0 Programming Complete Reference Guide

Organizing our code

Up to this point, we've been mostly coding at the REPL. Recently, in the previous chapter, we've started to rely more on the IDE to whip up short Julia files.

But, as our skillset grows and we develop more and more ambitious projects, so will grow the complexity of our programs. This, in turn, will lead to more lines of code, more logic, and more files—and more difficulties in maintaining and understanding all these down the line. As the famous coding axiom goes, the code is read many more times than it is written—so we need to plan accordingly.

Each language comes with its own philosophy and toolset when it comes to code organization. In Julia, we have files, modules, and packages. We'll learn about all of these next. ...
