How to output fewer records (by slice, limit, breaking the loop, etc)?

[truetonegroup]

How can I limit my output to fewer values than the original data?

My source has 50 records but I only want to end up with 5.

I was thinking that would work with a slice function or a {break;} when the i > 4 but I can't figure out where to put those in the code.

Thanks,
Andy

actualy the output is already an array.

So you can try with slice like this:

var dataTransform = DataTransform(data, map);
var result = dataTransform.transform();
console.log(result.slice(0,5));
