How do I make timeouts for different users in Node JS?

• 0
  I am making a telegram bot on Node, the essence of which is to create timers for users. The user can stop the timer at any time. How do I get him to clear his timer?
  
  My decision as a novice developer. Created an array, into which I add the {user_id, timeout} object when creating a timer. And when the user clicks on the stop, I make a clearTimeout for the desired object and then delete the object itself from the array.
  
  

  function clearUserTimeout(user_id) {
      const indexOfTimeout = timeouts.findIndex(item => item.user_id === user_id)
      if (indexOfTimeout !== -1) {
          clearTimeout(timeouts[indexOfTimeout].timeout)
          timeouts.splice(indexOfTimeout, 1)
      }
  }

  
  How to do it right?

  I would store in the object not timer objects, but only the time in UNIX, at the moment the user should stop the timer and make 1 common timer, which every second (1.5-2) runs through the objects and checks the time specified there, checks with the current and if it is less than the current one, it sends a message to the user and ends its timer by changing some bool variable, or simply by specifying the time to null.
