28. implement clearAllTimeout()

One possible solution could be:

// Create an object to keep track of all timeoutsconst timeoutIds = {};// Replace the original setTimeout with a new one that stores the timeout idwindow.setTimeout = function(callback, delay) {  const timeoutId = setTimeout(callback, delay);  timeoutIds[timeoutId] = true;  return timeoutId;};// Replace the original clearTimeout with a new one that clears all timeoutswindow.clearTimeout = function(timeoutId) {  clearTimeout(timeoutId);  delete timeoutIds[timeoutId];};// Implement clearAllTimeout function that clears all timeoutsfunction clearAllTimeout() {  Object.keys(timeoutIds).forEach(timeoutId => {    clearTimeout(timeoutId);    delete timeoutIds[timeoutId];  });}

In this solution, we create an object timeoutIds to keep track of all timeouts scheduled using our custom setTimeout function. When a new timeout is scheduled, we store its id in this object.

The clearTimeout function is replaced with a new one that first clears the timeout using the original clearTimeout function and then removes the timeout id from timeoutIds.

Finally, we implement the clearAllTimeout function that iterates over all timeout ids in timeoutIds and clears each timeout using the clearTimeout function. After that, we remove all ids from the timeoutIds object.

This way, we can use setTimeout and clearTimeout functions as before, but all timeouts can be cleared using clearAllTimeout function.
