    <p id="result">
      var regex_here = /^(0[1-9]|1[0-2])\/(0[1-9]|1\d|2\d|3[01])\/(0[1-9]|1[1-9]|2[1-9])$/;

            document.getElementById("result").innerHTML = "Your provided date is in Valid Format";
          document.getElementById("result").innerHTML = "Given date provided is in invalid format";
  1. Here, above we show you an example in JavaScript.
  2. For this first of all we here create a basic structure of html. For this we use html, head, title and body with script tag. We hope you know about the basic structure of html and which html tag is used for which concept.
  3. Now, when we look inside body tag. Here, we see some headings tag and a script tag. Heading tag again is a concept of html, whereas script relates to JavaScript.
  4. JavaScript is written always inside script tag. Where script is a paired tag so it also has a closing tag. Now inside these script tag, we write our JavaScript code.
  5. Now, here as we see in above codes. First of all we create some headings tag. Then our main code starts, in which paragraph tag is created from html. Here, as we see that we did not use our paragraph for any other purpose, we only give here a class to it.
  6. At next, there is our script tag in which we write our JavaScript codes. Now, we already know that we are going to use Regular expression here. So, we store our codes of regular expressions and then use a predefind date that is store in a variable to check whether the date is valid or not.
  7. This all validation is done using if condition. If our date is valid then a line containing text Your provided date is in valid format is display otherwise if the condition get wrong which means if it is in invalid format then Given date provided is in invalid format is executed.
