Create JavaScript function and call ingame with /js

[heid...@hotmail.com]

Hello everyone, 

as a complete newbie in JS and MC I wanted to create JS-functions which I can call using the /js command.
As a example I created "claims.js" with following content:

function getClaimCount(player)
{
 return server.pluginManager.getPlugin('griefprevention').dataStore
 .getPlayerData(player.getUniqueId())
 .getClaims().size();
}

How would I call this method? I tried /js getClaimCount(self) but with no success....

You have to "export" it.  See https://github.com/walterhiggins/ScriptCraft/blob/master/docs/API-Reference.md#module-loading

Ah, don't know how I missed that... export is working. Thank you very much!

And if I'd like to call a method from a different JS-File, do I need to export those functions as well?
I tried it like this:

require('./claims.js');

export.claims = function ClaimCount(player) {

return getClaimsCount(player); //function in claims.js

}

but it tells me that "claims" does not exist.

Stupid me ^^ 
Yes it has to.
