Mon 2021.04.12

Hi @coolio were you aware there is search dialog at the upper right of most Espruino site pages? A wealth of information may be obtained with use of this tool.

The full Javascript API may be obtained from the main page:

Menu >> Documentation >> API Reference

http://www.espruino.com/Reference#softwa­re

Which contains detail on all current functions to perform the task you are after.

Class JSON for data formatting

'understand if there is a way to load an array'

See ARRAY class:

'but there's no file system on the espruino'

See the FILE class:

I have been successful at off board storage with the AT24 series chips:
