Formatting Dates in JavaScript: A Guide to yyyy-mm-dd Format using jQuery

 Here's an example of a jQuery function that formats the date as "yyyy-mm-dd":

function formatDate(date) {
  const year = date.getFullYear();
  const month = String(date.getMonth() + 1).padStart(2, '0');
  const day = String(date.getDate()).padStart(2, '0');
  
  return `${year}-${month}-${day}`;
}

// Example usage:
$(document).ready(function() {
  const today = new Date();
  const formattedDate = formatDate(today);
  console.log(formattedDate);
});

In this example, we're using the $(document).ready() function to ensure that the code runs after the DOM has finished loading. Inside this function, we create a Date object for the current date.

The formatDate() function is the same as the previous example. It takes a Date object as input and returns the formatted date string in the "yyyy-mm-dd" format.

Finally, we call the formatDate() function with the current date and output the result using console.log(). You can modify the code to perform any desired action with the formatted date.

Make sure you include the jQuery library in your HTML file for this code to work properly.
