Very High-Level Languages (VHLLs, also known as scripting languages) posses the well-deserved place in the development process for desktop, servers, web, and to a lesser extent mobile systems. They offer such benefits as rapid prototyping, speed of the development, vast high-level libraries, ease of maintenance and support. The idea to use VHLLs for deeply embedded development, to benefit from the traits above, is a recent hot topic in IoT. This presentation surveys the challenges of using VHLLs on hundreds KB of ROM/tens KB of RAM devices, and compares different approaches of bringing VHLLs to IoT, based on the examples of MicroPython and JerryScript + Zephyr.js projects. Also includes recent development update for the mentioned projects.
