How to convert a timeformat in YYYYMMDDTHHMMSS in typescript

Question

I have a below date format need to convert it as

console.log(new Date(startDate)).toISOString();
console.log(new Date(endDate)).toISoString();

I need an output like this 20180928T00000 but which return 2018-11-01T00:00:00.000Z this format.

Current Output:
// startDate=2018-11-01T00:00:00.000Z
 //endDate=2018-12-01T00:00:00.000Z

Expected 
// StartDate=20181101T000000 
// endDate=20181201T0000000';

You can use a library like `moment`, or you can just use a regex to replace everything that's not a number — user184994, Nov 18 '18 at 13:15
@user184994 is there any builtin functions in moment to convert this — Mohamed Sahir, Nov 18 '18 at 13:20
Yep, `moment(new Date(startDate)).format('YYYYMMDDTHHMMSS');` — user184994, Nov 18 '18 at 13:22
thankyou one more help after T need to replace the system time to 000000 and end date should be 235959 as default . — Mohamed Sahir, Nov 18 '18 at 13:47
Then just do `moment(new Date(startDate)).format('YYYYMMDDT000000')` or use `235959` in the `endDate` example — user184994, Nov 18 '18 at 13:50

You could use Moment.js, however if it is just a once off and you do not want to import the whole library, I would suggest using regex to remove all none letters/numbers, then JS slice() method to remove last character.

const date = '2018-11-01T00:00:00.000Z'
const result = date.replace(/[^A-Za-z0-9]+/g,'').slice(0, -1)
console.log(result) // 20181101T000000000
