Convert date with forward slashes and partial time to Javascript date time

I have a date in a string format that looks like so:

"31/07/2022 16:00"

… and I want to change it to a valid Javascript date and time.

I’ve tried changing the forward slashes to '-' with this code:

let lala
let lalawood = '31/07/2022 16:00'
lala = lalawood.replace(///g, '-');
console.log(lala);  // outputs 31-07-2022 16:00

but it returns '31-07-2022 16:00' which is still an invalid date time. How can I convert this into a valid Date and Time so that I can use it to compare two dates programmatically?

Answer

The problem here is that you are using time in European format (DD/MM/YYYY), while JavaScript compiling it as American time format (MM/DD/YYYY), Here is a snippet that switch days and months to create a valid date

let s = '31/07/2022 17:30';
s = s.replace(/[^0-9 ]/g, " ").split(' ');
let d = new Date(s[2], s[1]-1, s[0], s[3], s[4]);
console.log(d);
