How do I set a task per hour?-CodePudding

I have the following array with all the hours of a working day:

let daySchedule = ["08:00", "09:00", "10:00", ... , "20:00"];

let task = 2; // the number of times a task should be performed during the day
let taskDescription = "Cleaning";

The output, in this case, should be:

08:00 - Coffee break
**09:00 - Cleaning**
10:00 - Coffee break
**11:00 - Cleaning**
12:00 - Coffee break
**13:00 - Cleaning**]

Etc... I tried to use a For loop and add "Cleaning" to the array, but how do I set it, so that it only displays every 2 rows?

Here is an example of using the modulo function to do what you want. For more info on modulo : https://en.wikipedia.org/wiki/Modulo_operation.

let daySchedule = ["08:00", "09:00", "10:00", "20:00"];
let task = 2; // the number of times a task should be performed during the day
let taskDescription = "Cleaning";
for(i=0;i<daySchedule.length;i  )
{
  if(i%task === 1)
  {
  console.log(daySchedule[i]   " "   taskDescription);
  }
  else
  {
  console.log(daySchedule[i]   " Coffee Break");
  }
  
}

So for your question, the code would be:-

let daySchedule = ["08:00", "09:00", "10:00", ... , "20:00"];

let task = 2;
let taskDescription = "Cleaning";
let temp= 0;

while(temp!=daySchedule.length){
     temp%task===1 
     ? (console.log(daySchedule[temp]   " "   taskDescription)) 
     : (console.log(daySchedule[temp]   " Coffee Break"))
     temp  ;
 
}

Tip :- Try to use ternary operator instead of if-else for better code quality and understanding
