POPL (Principles of Programming Languages)

POPL, or Principles of Programming Languages, is a field of study focused on understanding the fundamental ideas behind how programming languages are designed and work. It explores concepts like syntax (structure), semantics (meaning), types (rules for data), and how languages help us instruct computers. The goal is to develop better, more reliable, and more efficient languages by analyzing their core principles, enabling programmers to write clearer, safer, and more effective software. POPL involves both theoretical research and practical application, shaping the tools programmers use daily.
