JavaScript Introduction to jQuery DOM Traversal Why We Traverse the DOM

What does the parameter in the JQuery forEach() method return?

I'm not sure what the returned value of the parameter is in the Jquery forEach() method

Could someone explain what is happening here?

Thanks

var list = [
  {
    name: "kris"
},
  {
  name: "bob"
},
  {
  name: "jon"
}
];

list.forEach(function(students) {
   console.log(students.name);
});

Also, a side question is: is the forEach() an older method. Has it been replaced by each()...?

The .forEach method is part of JavaScript, it's not jQuery.

The first argument passed to the callback is the current array element. Optional second and third arguments are the element index and the array itself, respectively.

jQuery has two different .each methods, one works with arrays but the syntax is slightly different. The other is specifically for jQuery objects.
