Perl Data Structures: Mastering Context and Array References

Perl's context-sensitive nature is both its greatest strength and a common source of confusion. In this comprehensive text-only course, you will master the fundamental mechanics of how Perl handles arrays, list flattening, and references, enabling you to write cleaner and more predictable code. What you'll learn: Understand the critical difference between scalar and list context in Perl; Manage array interpolation and flattening inside larger data structures; Build nested data structures using array references and proper dereferencing; Apply modern Perl best practices including strictures, warnings, and clean syntax; Practice debugging context-related issues through targeted written exercises. We begin with core terminology and context definitions before advancing to nested data structures and reference manipulation, building your confidence step-by-step. This course is designed for beginners who know basic Perl syntax and want to master data manipulation, with no advanced prerequisites required.
