JavaScript code size

Hi, @Gordon!
You are right!!!!
I think most persons do not have a correct understanding of what is going under the curtain!
I mean, doing really real time I/O in such a high level language as Espruino / JavaScript are, as simply as it is now, is quite a challenge very few of them would have tried, say using Arduino C++ approach!
Furthermore we all try to do this on very small platforms, happily forgetting any realistic constraints of memory sizes or computation time/responsiveness.
Espruino definitely allows to make it, reducing the source code to a minimal size.
I think, just as every one else, I hit the available ram size wall.
So, to make it concrete, I would state that any ram saving technique is good to use but, expecting a massive ram requirement reduction, is just an illusion. You have to choose an appropriate platform to your application!
So, you are right when you consider that Espruino is targeted at small, very energy saving, platforms...
Now it is clear that tomorrow will be brighter than yesterday... Maybe...
It's a time/effort/cost alternative consideration.
Should this community finds a clearly simple, universal, solution let's do it.
I doubt...
Go on!
You know what you are doing as a software / hardware designer or architect. It's more than obvious looking at the Espruino's projects.
