InDesign JS arrays quesion...

Hi @deckarduk ,

let's see:

"Looping the array with increments of 2 would be one solution."

Exactly this.

Examples:

var a =
[
	0 ,
	1 ,
	2 ,
	3 ,
	4,
	5

];

var resultArrayStartWithZero = [];

for( var n=0; n<a.length; n=n+2 )
{
	resultArrayStartWithZero[resultArrayStartWithZero.length++] = n ;
};

// Result: 0,2,4

resultArrayStartWithOne = [];

for( var n=1; n<a.length; n=n+2 )
{
	resultArrayStartWithOne[resultArrayStartWithOne.length++] = n ;
};

// Result: 1,3,5

I suppose whatever you do would involve a loop mostly, unless you join the array values into a string and do some Grep magic. Is running a loop troublesome in your case?
