How to delete data by mask in Javascript using .replace or something else?

I’m getting data in the form of date and time:

Monday Jan 23 10:14:27 2024

How in Javascript using .replace to remove everything except time without seconds:

10:14

.

Please tell me, because I am already lost in these regular expressions.
Thank you all.

    Use String.prototype.match

    const reg = /d{2}:d{2}/
const str = 'Monday Jan 23 10:14:27 2024'
const time = str.match(reg)[0]
console.log(time)

    You could simply convert this string to date and extract the required information from it.

    const theDate = new Date('Monday Jan 23 10:14:27 2024');
const displayValue = `${theDate.getHours()}:${theDate.getMinutes()}`;

console.log(displayValue); // 10:14
