About the use of the .each() method in this task

I'm confused about the way the .each() method is used in this lesson. The following is provided as example code for us to build off:

$(document).ready(function () {
  $.getJSON('../data/employees.json', function (data) {
    var statusHTML = '<ul class="bulleted">';
    $.each(data,function (index, employee) {
      if (employee.inoffice === true) {
        statusHTML +='<li class="in">';
      } else {
        statusHTML +='<li class="out">';
      }
      statusHTML += employee.name + '</li>';
    });
    statusHTML += '</ul>';
    $('#employeeList').html(statusHTML)
  });

Im confused as how how the .each() method is going over the results of the JSON file when it is attached to the JQuery object. It seems like the function is operating on the first argument (data) but I checked the JQuery documentation and can't find any similar examples.

I thought the .each() method only worked on the object it is attached to?

There's a difference: For this situation: http://api.jquery.com/jquery.each/

For other situations: https://api.jquery.com/each/

It all depends on what you're doing. In this case you are calling jquery.each aka $.each(array, callback(index, value)).

The other .each method is typically used on jQuery objects like $("li") objects, for example.
