If you're ever needing to run a loop and break for a set period of time before continuing a loop, this should help do that

recursiveSetTimeout.js

var myArr = [],
    count = 0,
    batches = 0,
    newArr = [];

for (var i = 0; i < 103; i++) {
    myArr.push(i);
    if (myArr.length > 9) {
        batches = Math.ceil(myArr.length / 10);
    }
}
console.log('total batches = ' + batches);

function splitArray() {
    // document.getElementById('text').innerHTML = newArr;
    newArr = myArr.splice(0, 10);
    //  console.log('batch ' + count + ' out of ' + batches);
    //  console.log(newArr);

    setTimeout(function() {
        console.log('batch ' + (count + 1) + ' out of ' + batches);
        count++;
        console.log(newArr);
        if (count < batches) {
            console.log('waiting...')
        } else {
            console.log('process complete');
        }
        if (count < batches) {
            splitArray();
        }
    }, 3000);
}
splitArray();

console.log('--------------');
