Why isn't this variable range's data changing with the new variable set?

Question

Why doesnt the logged data change with the variable ranges data?
Im trying to build a function that will cycle through a column and will stop once it passed the end date.

function january() {
    var i = 6;
    var x = 1;
    var cellPos = theList.getRange(i, x);
const start = new Date("01/01/2022");
const end = new Date("01/31/2022");
var loop = cellPos.getValue(); 

while (loop < end){
    Logger.log(loop);
    var i = i+1;
    Logger.log(i);
    Logger.log(loop);

}
}

Answer 1

function january() {
    var i = 6;
    var x = 1;
    var ss = SpreadsheetApp.getActiveSpreadsheet();
    var sh = ss.getSheetByName("Test");
    var data = sh.getDataRange().getValues();
    //var cellPos = theList.getRange(i, x);
    //const start = new Date("01/01/2022");
    var end = new Date("01/31/2022");
    var loop = data[5][0]; // Cell row 6 column 1

  while (loop < end){
    Logger.log(i);
    loop = data[i][0];  // Starts at 6
    Logger.log(loop);
    i = i+1;
  }
}
