Timeout Object to prevent duplicate setTimeout calls

Timeout.js

TimeHolder = {};
    TimeHolder.delay = 2000;
    TimeHolder.value = null;
    TimeHolder.cancel = function cancel() {
        clearTimeout(TimeHolder.value);
        TimeHolder.value = null;
    };
    window.TimeHolder = TimeHolder;
    if (TimeHolder.value === null) {
      // Attempting to set a timeout call so that the class does not immediately trigger again.
          TimeHolder.value = setTimeout(function checkOverflownContent() {
              // Do stuff.
              TimeHolder.cancel();
          }, TimeHolder.delay);
      }
