[SOLVED] ADS1x15 module is not really compatible with ADS1115

Thank you @Gordon. I tried to implement this feature according to your recommendation and made a pull request here: https://github.com/espruino/EspruinoDocs/pull/665

However, when testing, I got this error

Uncaught Error: Function "connect" not found!
 at line 96 col 26 in ADS1X15
function ADS1X15(i2c,opts={part:"ads1015"}) {
                         ^
 at line 198 col 30
    ads = require("ADS1X15").connect(i2c,{part:"ads1115"});
                             ^
in function "onInit" called from line 212 col 8
onInit();

It is most probably a very noob, basic javascript error. Could you help me figure out what's going wrong with the way I made the change?
