Tell us what’s happening:
Describe your issue in detail here.

Your code so far

// Setup
const lastName = "Lovelace";

// Only change code below this line
const lastLetterOfLastName = lastName[lastName.length-1]; // Change this line

wondering why you have to write lastName[lastName.length-1] instead of just writing lastName.length-1. seems like you are calling lastName twice.

lastName isn’t a function, so you aren’t calling it.

You are using one piece of information about the string to get another piece of information about the string.

This is how long the string is. It is a number. You are using the number and bracket notation to get the letter that is at the end of the string.
