JavaScript JavaScript Loops, Arrays and Objects Tracking Data Using Objects The Student Record Search Challenge Solution

I' m missing something....

why are we using student.name on the function getStudentReport before we assigned students[i] to it...

I mean, is on the for loop where we assigned to the empty var student, the value of students[i]...

In the for loop, the student variable is given the value of students[i] before the getStudentReport function gets called, so the value will be updated when it runs.

It is a little confusing when reading the code from top to bottom. Just remember that variables may change values before the function gets called in the code.

In this case, student is being used as both a shorthand way of writing students[i], and to make it more understandable (i.e., we are referring to one particular student out of an array of students).

yep and thanks, but what I still don't get is, the array's name is students, student is an undefined variable (var student;) so, if I say student.name for JS it should meant nothing... My main problem is that we assigned the value of students[i] to the variable student way after in the for loop... It's kinda confusing...
