Answer 2

I personally use momentjs

momentjs format syntax

for your case: moment('23 MAY 2022').format("DD/MM/YYYY")

Answer 3

I'd suggest trying luxon , an evolution of moment.js.

You can use DateTime.fromFormat() to parse the input string, then use DateTime.toFormat() to output the desired result:

 const { DateTime } = luxon; const input = '23 MAY 2022'; const dt = DateTime.fromFormat(input, 'dd MMM yyyy'); const result = dt.toFormat('dd/MM/yyyy'); console.log('Result:', result)
