Continue iterating through the range of dates until the first date comes before the second date

Question

Continue iterating through the range of dates until the first date comes before the second date

I have a pair of Unix timestamps:

let start: number = 1632988953;
const end: number  = 1638259353;

My goal is to iterate over these two dates, recalculating the new start date in each iteration.

To achieve this, I am utilizing a while loop as shown below:

const datesArray = [];
while (start <= end) {
    let newDate = dayjs.unix(start).add(5, 'day').unix();

    datesArray.push(newDate);
    
    start = newDate;
}

However, upon executing this while loop within the function, it results in infinite iterations which ultimately leads to high resource consumption and crashes the browser. Can anyone help me identify what might be causing this issue?

let start = 1632988953;
const end  = 1638259353;

let condition = true;
console.log("before : ",condition);
const datesArray = [];
while (start <= end) {
    let newDate = dayjs.unix(start).add(5, 'day').unix();
    datesArray.push(newDate);
    start = newDate;
    condition = start <= end;
}
console.log("after : ",condition);
