Since you attached the .forEach method to the array of students what it does is go through each item in that array one by one doing whatever you tell it to do in the callback function. So basically in your mind picture that student param as that first student object in your students array. Heck, name it that to picture exactly what forEach is doing if it is helpful. Now in that callback you are simply just accessing that student object like how you would any other in dot notation and then logging it to the console. The forEach loop will then go to the next student object and so on until there are no more items left in the array.
