How to get all dates between two dates in JavaScript?

To get all dates between two dates, go through the following steps:

First, create an empty array that will store all the dates between 2 dates.
After that, create a temporary Date object which is equal to the starting date of the range.
Then, increment the temporary Date object by 1 and push the Date object to the array.
Repeat step 3 until all the dates in a range are covered.

Let's understand the process with the help of an example:

Suppose you want to get all the dates between 27th January 2022 and 19th February 2022.

let startDate = new Date(2022, 0, 27);
let endDate = new Date(2022, 1, 19);
let dates = [];

console.log(startDate.toString());
console.log(endDate.toString());

let tempDate = new Date(startDate.getTime());
while(tempDate <= endDate){
  dates.push(new Date(tempDate));
  tempDate.setDate(tempDate.getDate() + 1);
}

If you don't want to include the starting and ending date, then increment the temporary Date object by 1. Also, change <= to <.

let startDate = new Date(2022, 0, 27);
let endDate = new Date(2022, 1, 19);
let dates = [];

console.log(startDate.toString());
console.log(endDate.toString());

let tempDate = new Date(startDate.getTime());
tempDate.setDate(tempDate.getDate() + 1);

while(tempDate < endDate){
    dates.push(new Date(tempDate));
    tempDate.setDate(tempDate.getDate() + 1);
}
