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

Using ES6 you have Array.from meaning you can write a really elegant function, that allows for dynamic Intervals (hours, days, months).

function getDates(startDate, endDate, interval) {
const duration = endDate - startDate;
const steps = duration / interval;
return Array.from({length: steps+1}, (v,i) => new Date(startDate.valueOf() + (interval * i)));
}
const startDate = new Date(2017,12,30);
const endDate = new Date(2018,1,3);
const dayInterval = 1000 * 60 * 60 * 24; // 1 day
const halfDayInterval = 1000 * 60 * 60 * 12; // 1/2 day

console.log("Days", getDates(startDate, endDate, dayInterval));
console.log("Half Days", getDates(startDate, endDate, halfDayInterval));
