Confused on how to access multiple objects in a variable.

Part II (Optional)

Now, given the following dictionary:

var users = { 'Students': [ {first_name: 'Michael', last_name : 'Jordan'}, {first_name : 'John', last_name : 'Rosales'}, {first_name : 'Mark', last_name : 'Guillen'}, {first_name : 'KB', last_name : 'Tonel'} ], 'Instructors': [ {first_name : 'Michael', last_name : 'Choi'}, {first_name : 'Martin', last_name : 'Puryear'} ] } Create a program that prints the following format (including the number of characters in each combined name):

Students 1 - MICHAEL JORDAN - 13 2 - JOHN ROSALES - 11 3 - MARK GUILLEN - 11 4 - KB TONEL - 7 Instructors 1 - MICHAEL CHOI - 11 2 - MARTIN PURYEAR - 13

looks like a for loop to me

//this will give you access to the 2 objects const students = users.students const instructors = users.instructors

//iterate through the array and give you the values of the name length for (let i = 0; i < students.length; i += 1) { let name = students[i].first_name + " " + sudents.[i].last_name; let nameLength = name.length }) }

its not the whole solution but it should get you part of the way there :) i could also be wrong.. never rule that out!

for some reason the teehouse forum thing is messing with the formatting, i hope you can still read it

It's a bit like peeling an onion. Think in layers.

  • users is the object itself
  • users.Students would be the array of student objects
  • users.Students[i] would be one student object (at index "i")
  • users.Students[i].first_name would be that student's name property
