Google Apps Script return date between a range of dates in an array

Question

I have an array of dates. I want to return the dates between January 01, 2022 and December 31, 2022.

When I run the cut below, it doesn't return anything. This is one of many different loop variations I've tried to no avail. Please help TIA

var start = new Date(2022, 0, 01); //returns Sat Jan 01 00:00:00 GMT-06:00 2022
var end = new Date(2022, 11, 01); //returns Sat Dec 31 00:00:00 GMT-06:00 2022
var arr = [Fri Dec 03 2021 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Dec 10 2021 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Dec 17 2021 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Dec 24 2021 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Dec 31 2021 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Jan 07 2022 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Jan 14 2022 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Jan 21 2022 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Jan 28 2022 00:00:00 GMT-0600 (Central Standard Time),
           ...](**output** NOT the actual script)
for(var i=0; i<=arr.length; i++){
   if(arr[i] >= start && arr[i] <= end){
      Logger.log(arr[i]);
   }
}

Modification points:

From your script, I couldn't understand the value of arr. Because in your script, when you save the script, an error occurs. So I'm worried that your actual script is different from your showing script. If each value of arr is the string type like Fri Dec 03 2021 00:00:00 GMT-0600 (Central Standard Time), please enclose it using the double or single quotes.
- If my guess of your script is not correct, please provide your actual script.
In order to compare the date, I think that this thread will be useful. Ref

When these points are reflected in your script, it becomes as follows.

Modified script:

var start = new Date(2022, 0, 01); //returns Sat Jan 01 00:00:00 GMT-06:00 2022
var end = new Date(2022, 11, 01); //returns Sat Dec 31 00:00:00 GMT-06:00 2022
var arr = [
  "Fri Dec 03 2021 00:00:00 GMT-0600 (Central Standard Time)",
  "Fri Dec 10 2021 00:00:00 GMT-0600 (Central Standard Time)",
  "Fri Dec 17 2021 00:00:00 GMT-0600 (Central Standard Time)",
  "Fri Dec 24 2021 00:00:00 GMT-0600 (Central Standard Time)",
  "Fri Dec 31 2021 00:00:00 GMT-0600 (Central Standard Time)",
  "Fri Jan 07 2022 00:00:00 GMT-0600 (Central Standard Time)",
  "Fri Jan 14 2022 00:00:00 GMT-0600 (Central Standard Time)",
  "Fri Jan 21 2022 00:00:00 GMT-0600 (Central Standard Time)",
  "Fri Jan 28 2022 00:00:00 GMT-0600 (Central Standard Time)",
];
for (var i = 0; i <= arr.length; i++) {
  if (new Date(arr[i]).getTime() >= start.getTime() && new Date(arr[i]).getTime() <= end.getTime()) {
    console.log(arr[i]);
  }
}

What Tanaike mentioned is correct, it should be a string in your array and missing quotes then you can do

arr.filter(dates => new Date(dates) >= start && new Date(dates) <= end );

I was able to figure it out thanks for your input. The problem was I needed to set arr[i] to new Date(arr[i]). Below is the updated code.

var start = new Date(2022, 0, 01); //returns Sat Jan 01 00:00:00 GMT-06:00 2022
var end = new Date(2022, 11, 01); //returns Sat Dec 31 00:00:00 GMT-06:00 2022
var arr = [Fri Dec 03 2021 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Dec 10 2021 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Dec 17 2021 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Dec 24 2021 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Dec 31 2021 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Jan 07 2022 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Jan 14 2022 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Jan 21 2022 00:00:00 GMT-0600 (Central Standard Time), 
           Fri Jan 28 2022 00:00:00 GMT-0600 (Central Standard Time),
           ...](**output of the array** NOT the actual script)
for(var i=0; i<=arr.length; i++){
   var arrI = new Date(arr[i]);
   if(arrI >= start && arrI <= end){
      Logger.log(arrI);
   }
}
