Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.

I removed my GPS user code (to save code space for this testing) and did the following testing below:
Summary:
@Gordon Removing "all" text/comments from user code saved 149 in memory usage.
@DrAzzy - fiddling with optimizations produced very mixed results.
Optimization #5 reduced memory usage but gave minification errors?
It looks like more work is needed in the optimizations for the Espruino?
Note: I did not try "all" combinations optimizations.
More work is needed in increasing my user application memory usage ...
