Welcome to an insightful journey through the world of functional programming, as we delve into the depths of the Red language. Today, we'll learn to appreciate the power and simplicity of Red, using it to create a GUI calculator with just 14 lines of code! In contrast to traditional methods like Qt, this is faster, sleeker, and perfect for agile prototyping.

We explore Red's long history and explain some of the key GUI features of this mighty, albeit less known, language. Red's strength lies in its ability to produce one executable file, an utmost convenience for any developer. As we dive deeper, you'll understand why Red is the hidden gem in the sea of functional programming languages.

Our main example, a GUI calculator, showcases Red's prowess. This straightforward application, taking more than a hundred lines in Qt, is reduced to a mere 14 lines in Red. We believe this exemplifies the agility of #RedProgramming and the brilliance of #Functional coding.
