The in operator in javascript is for key's in objects.

You can use Array.indexOf() to check if an element exists in the array, it will return -1 if it doesn't exist

Now,

You can check if(RatecardIDs.indexOf(parseInt(cellValue))>-1) {...}

In javascript in operator used to get keys in an object. You can use javascript's Array.indexOf or jquery's inArray for that.

Just use like bellow

RatecardIDs=[2, 22, 23, 25];

if(RatecardIDs.indexOf(parseInt(cellValue))>-1){
 ...
}

Or using jquery

if($.inArray(parseInt(cellValue),RatecardsId)>-1){
  ....
}
