const oldString = "The quick brown fox jumps over the lazy dog.";

// push the ranges
gatheredRanges.push(35, 43, "little Red Riding Hood");
gatheredRanges.push(4, 19, "bad grey wolf");

// retrieve the merged and sorted ranges by calling .current()
assert.deepEqual(gatheredRanges.current(), [
  [4, 19, "bad grey wolf"],
  [35, 43, "little Red Riding Hood"],
]);
