**Which of the Following Is a Key Feature of a Functional Programming Language?** When developers and tech enthusiasts ask, *“Which of the following is a key feature of a functional programming language?”* they’re tapping into a growing conversation about how modern software design is evolving. Functional programming isn’t just a niche concept anymore—it’s shaping how major tech companies build scalable systems, improve reliability, and enhance team collaboration. Curious about what makes it different? Understanding this core concept helps developers grasp why functional paradigms are increasingly sought after in both emerging startups and established enterprises. At its heart, a functional programming language centers on treating computation as mathematical functions—ideally pure, predictable, and free from side effects. Unlike imperative or object-oriented approaches, functional languages emphasize expressing *what* should be computed rather than *how*. This shift reduces hidden dependencies and enhances code clarity, making programs easier to debug, test, and maintain. ### Why Is This Feature Gaining Traction in the US Tech Scene?
