How to add specific characters in between values of a JavaScript date?-CodePudding

I am trying to format a date in JavaScript to fit a specific format.

My desired format is 29-Jan-2021

With the below code I have managed to generate "29 Jan 2021":

var newDate = new Date('2021-01-29T12:18:48.6588096Z')

const options = {
  year: 'numeric',
  month: 'short',
  day: 'numeric',
};

console.log(newDate.toLocaleString('en-UK', options))

Can someone please show me how I can add - between the day, month, & year in the date above?

Well you if you have already able to find the string close to your answer you can achieve your solution with either of the two methods.

Either you can use replaceAll() or replace(). Both will be able to solve the issue.

let dateFormat = "29 Jan 2021"
console.log(dateFormat.replaceAll(" ","-")) // 29-Jan-2021
console.log(dateFormat.replace(/ /g,"-")) // 29-Jan-2021

Well I would suggest you to use replace() over replaceAll as some browsers do not support replaceAll(). Do check replaceAll support.
