How to split array into even chunks?

[Marcus]

I am seeking to split and array into even chunks of a specific size but having trouble on how to incorporate the .splice() method within my for loop 

  var consumerList = [];
	var cases = new GlideRecord("sn_customerservice_case");
    cases.addQuery('parent', current.sys_id);
    cases.query();
    while (cases.next()) {
        consumerList.push(cases.consumer.email);
        var splitList = consumerList.split(",");
        for (var i = 0; i < splitList.length; i++) {
          gs.print(splitList[i]);
    }
    }

Hi there, can you try something like the below please

  var consumerList = []; // you are defining an array here
    var chunkSize = 100; // add your chunk size
    var cases = new GlideRecord("sn_customerservice_case");
    cases.addQuery('parent', current.sys_id);
    cases.query();
    while (cases.next()) {
        consumerList.push(cases.consumer.email); // you are pushing items to your array
        var splitList = consumerList.split(","); // you are calling split on something that is already an array (is there a need for this?)
        for (var i = 0; i < splitList.length; i++) {
          var chunk = splitList.slice(i, i + chunkSize); // this will be an array of 100 email strings
    }
