compute unzip

compute.unzip( arr[, idx] )

Unzips a zipped array (i.e., a nested array of tuples).

var arr = [ [1,'a',3], [2,'b',4] ];

var out = compute.unzip( arr );
// returns [ [1,2], ['a','b'], [3,4] ];

To unzip specific tuple elements, you can provide an array of indices as an optional second argument.

var arr = [ [1,'a',3], [2,'b',4] ];

var out = compute.unzip( arr, [0,2] );
// returns [ [1,2], [3,4] ];
