Concept: Dynamic time division flow control

TimeDivisionFlowControl.js

// Typically, mordern client systems limit it 60 milliseconds
const FRAME_LIMIT = 100 // milliseconds, naaive

const TDFC = (MAXROW, cb) => {
  return new Promise(resolve => {
    const maxRow = MAXROW;
    let cursor = 1; // start point
    let partialMax = 10; // minimal loop block
    let before = new Date().getTime();
    let result;
    const loop = () => {
      for (; cursor <= partialMax && cursor <= maxRow; cursor += 1) {
        result += cb(cursor); // Sometimes it can be an addition or append operation
      }
      if (cursor < maxRow) {
        const after = new Date().getTime();
        const timeDiff = after - before || 1;
        const perMillisec = timeDiff / partialMax;
        partialMax = parseInt(FRAME_LIMIT / perMillisec, 10) + cursor;
        before = after;
        setTimeout(loop, FRAME_LIMIT);
      } else {
        resolve(result);
      }
    };
    loop();
  });
};
