Hello everyone, I need to make a function that will display certian text using For loop. Can anyone help me?

const students = [
{ name: “John”, city: “New York” },
{ name: “Peter”, city: “Paris”},
{ name: “Kate”, city: “Sidney” }
]

I need to have console.log to display "<Name> lives in <city>"

Hi,

I was going for

for(let i = 0; i  < students.length; i++){
console.log(students.name[i] + " "+ "lives in" + " " + students.city[i]);
4

Good first try.

So what does the error say?
And why?

5

I got "Uncaught SyntaxError: Invalid or unexpected token "

And I have no idea why :sweat_smile:

6

Mostly caused by a wrong bracket.

Did you close all open brackets like () and {}?

7

Now I got this “TypeError: Cannot read property ‘0’ of undefined”

Nice!

So there’s this thing students.name[i].

What do you want to do there?

console.log(students.name[i] + " "+ “lives in” + " " + students.city[i]);
