However, when you come to writing a script that actually does something useful, your code is likely to get more complex. As you add more code to the script, it becomes harder to read in one chunk. If you print it on paper, your scripts will undoubtedly stretch across multiple pages. As the code becomes more complex, it’s easier for bugs and errors to creep in, and the poor layout of the code will make these harder to find and fix. The most common technique programmers use to manage complexity is called modularization.
