Javascript - get array of dates between 2 dates

Question

var range = getDates(new Date(), new Date().addDays(7));

I\'d like \"range\" to be an array of date objects, one for each day between the two dates

Answer 1

This is how i like to do it

// hours * minutes * seconds * milliseconds
const DAY_IN_MS = 24 * 60 * 60 * 1000

/**
 * Get range of dates 
 * @param {Date} startDate 
 * @param {Number} numOfDays 
 * @returns {array}
 */
const dateRange = (startDate, numOfDays) => {
    const startDateMs = startDate.getTime()

    // get array of days and map it to Date object
    return [...Array(numOfDays).keys()].map(i => new Date(startDateMs + i * DAY_IN_MS))
}
