you can’t define the same variable twice. Define the variable only once, then change the array using bracket notation.

you need to make New York and Mumbai two different strings, not only one

like London is its own string, you need to have New York be a string wrapped in quotes, and Mumbai also a string wrapped in quotes

here two examples from your own code:

delete this line, and change the last eleement of the array using bracket notation to access only the third element

also London needs an upper case L

Ive wrote something like that :

let cities = ["London","New York","Mumbai"];
console.log(cities);
cities[cities.length-1].
let cities = ["London","New York", "Mexico city"];
console.log(cities);

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

you have two syntax issues:

the dot after the square bracket

this line as a whole, delete it

you did not try to reassign the 3 element of the array yet

HI @fate1 !

You should do the following to pass the test

as mentioned, you need to delete this here

Then you need to review the previous step here

you see how you updated the last element of the rows array to 10 here?

rows[rows.length - 1] = 10;

you need to do something similar for the cities array and the string "Mexico City"

it looks like you were trying to do that here

but that dot shouldn’t be there and you are missing the assignment of the string "Mexico City"

look back at the previous step so you can see correct syntax

once you fix that, then the test should pass

hope that helps
