jQuery Code Sample to request Data AJAX

$(document).ready(function() {
  $.getJSON('/users', function(data) {
    console.log(data);
  });

  $('.btn').click(function() {
    var user = $('input[name="user"]').val();
    var pass = $('input[name="pass"]').val();
    $.post('/users', $('#myform').serialize())
      .done(function(data) {
        console.log(data);
      });
  });
});

This code will make a GET request to /users endpoint when the page is loaded, and make a POST request to the same endpoint when the button with class btn is clicked. It will serialize the data from the form with id myform and log the response from the server to the console.
