How to Convert a dd-mm-yyyy String to a Date in JavaScript

In JavaScript, converting a string representing a date in the dd-mm-yyyy format to a Date object can be challenging due to the presence of hyphen symbols "-" as separators.

One common approach is to split the string into its components using the "-" as a delimiter and then manually create a Date object using the split parts. For example:

var dateString = "15-05-2018";
var dateParts = dateString.split("-");
var date = new Date(dateParts[2], dateParts[1] - 1, dateParts[0]);

Alternatively, regular expressions can be used to extract the date parts from the string:

var date = new Date("15-05-2018".replace( /(\d{2})-(\d{2})-(\d{4})/, "//"))

In cases where simplicity and performance are prioritized, it may be more convenient to define a reusable function to handle the conversion:

function toDate(dateString) {
  var dateParts = dateString.split("-");
  return new Date(dateParts[2], dateParts[1] - 1, dateParts[0]);
}

var date = toDate("15-05-2018");

For JavaScript versions supporting destructuring, a more concise approach is available:

const toDate = (dateString) => {
  const [day, month, year] = dateString.split("-");
  return new Date(year, month - 1, day);
};

const date = toDate("15-05-2018");

By selecting the appropriate method, developers can easily convert dd-mm-yyyy strings to Date objects, ensuring accurate date handling in their JavaScript applications.
