 This shift doesn't just make development easier; it makes it faster. What used to take weeks in C can now be done in days. Lua's simplicity encourages rapid prototyping and quick iteration, which is essential in modern IoT and embedded development, where both time-to-market and security are critical. For a conceptual overview of why this hybrid development model is so powerful, check out the tutorial `Why Smart C Coders Love Lua <https://realtimelogic.com/articles/Using-Lua-for-Embedded-Development-vs-Traditional-C-Code>`_.
