> Javascript is in a similar situation with node.js ported to a Cortex-M3 ARM microcontroller Well, yes and no. Yes, there are JavaScript environments ported to different platforms, including microcontrollers. But no, JavaScript is not compiled to native code ahead of time nor does it run without a big runtime system. While there is some technical trickery involved in getting JavaScript running on different platforms, I find the new LLVM-based languages that run on bare metal much more interesting. Due to its nature, even the best of JavaScript implementations waste quite a lot of resources compared to native code. While computers are fast enough and have enough memory not to notice the difference, it's still consuming more battery power and producing more heat than executing native code. And it's power and thermals that have been the limiting factor of computational power for the past decade. |
