I am getting date in this format 01/01/2022 (dd/mm/yyyy). And i have to convert it into ISO format("2022-01-01T00:00:00.000+01:00"). I've tried but I get invalid time value error. 
const newDate ='01/01/2022' 
"2022-01-01T00:00:00.000+01:00"

    try this
var str = "25/09/2019";
darr = str.split("/");    // ["25", "09", "2019"]
var ISOFormat = new Date(parseInt(darr[2]),parseInt(darr[1])-1,parseInt(darr[0]));
console.log(ISOFormat.toISOString());
