The evt argument enables you to hook into form functionality and information . It doesn't have to be named evt ... You can name it however you please. For example, you could write

$(form).submit(function(e){
   e.preventDefault(); // prevent default behaviour 
   // validate form
   // submit form info via ajax 
});

Look into this [stackoverflow question](https://stackoverflow.com/questions/35936365/javascript-what-exactly-is-parameter-eevent-and-why-pass-it-to-javascript-fun) for a more info.
