  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. Here, as we see in form we create two fields for password and confirm password with one button to submit form. At next on key up on confirm password and button click our different functions get called.
  6. At first, our both the fields are required and they must be matched. If they are not matched then error messages will be showed as per requirement. Rest you can see the above code for better understanding.
