Challenge: Basic JavaScript - Use Bracket Notation to Find the Last Character in a String

Link to the challenge:

LastName.length - a

What is LastName and why - a?


Look at the example code again.

const firstName = "Ada";
const lastLetter = firstName[firstName.length - 1];

firstName.length is using the length property on the string stored inside the firstName variable and - 1 is used because the index is zero-based.

const firstName = "Ada";
const lastLetter = firstName[firstName.length - 1];

console.log(firstName.length); // 3
console.log(firstName[0]); // A
console.log(firstName[1]); // d
console.log(firstName[2]); // a
console.log(firstName.length - 1); // 2
