YYYY-MM-DDTHH:mm:ss±hh:mm to YYYYMMDDHHmms

Question

What is the best way to convert YYYY-MM-DDTHH:mm:ss±hh:mm(string) to YYYYMMDDHHmmss(string) using regex or any other way?

For eg: 2020-02-27T01:23:44-05:30 to 20200227012344

Can someone help me here?

var moment = require("moment"); var input = "2020-02-27T01:23:44-05:30"; var converted = moment(input).format("YYYYMMDDHHmmss"); console.log(converted); — joy08, Feb 27 '20 at 11:25

Fastest way for me. Relies on constant size of input string.

const input = "2020-02-27T01:23:44-05:30"
const input2 = "2020-02-27T01:23:44+05:30"

const testOutput ="20200227012344"

const transformTime = time => time
     .split('-')
     .join('')
     .split('+')
     .join('')
     .split(':')
     .join('')
     .split('T')
     .join('')
     .substring(0, 14)

console.log(transformTime(input) === testOutput)
console.log(transformTime(input2) === testOutput)

for the first split, it is not confirmed that it is a - or +. So we cannot directly go like this. – santhosh Feb 27 '20 at 11:13
Just split on that too. I've updated it. – Josh Wulf Feb 27 '20 at 11:14

You could try this regex

(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2})\+(\d{2}):(\d{2})
