save(); dump(); load(); what about clear() -> use reset(true)

On ESP8266 there are some lines of code after reset() coming from jshReset(), so reset();save(); is not a appropriate option.

The reason behind this is, that saved code caused trouble on ESP8266 when updating to a new release in the past. Sure "erase_flash" is an option, but works only over serial connection AFAIK.

But require("Flash").erasePage(addr); will do.

So this is my clear();

var clear = function() {
        require('Flash').erasePage(your_save_code_page);
};

>clear();
=undefined
>load();
=undefined
No code in flash!

I purposely did not name addr. If this is helpful for you, than lookup it up at the Espruino ESP8266 board documentation page section "SAVING CODE TO FLASH"
