Using the map method on the authors array, create an array of full name strings, comprising the first name, then a space

Question

I am wondering to know what am I doing wrong here. https://teamtreehouse.com/library/javascript-array-iteration-methods/combining-array-methods/working-with-objects

app.js

const authors = [
  { firstName: "Beatrix", lastName: "Potter" },
  { firstName: "Ann", lastName: "Martin" },
  { firstName: "Beverly", lastName: "Cleary" },
  { firstName: "Roald", lastName: "Dahl" },
  { firstName: "Lewis", lastName: "Carroll" }
];
let fullAuthorNames;

// fullAuthorNames should be: ["Beatrix Potter", "Ann Martin", "Beverly Cleary", "Roald Dahl", "Lewis Carroll"]
// Write your code below
const fullAuthorNames= authors.map(author=>`${author.firstName} ${author.lastName}`);
console.log(fullAuthorNames);

look at what the error is telling you - fullAuthorNames has already been declared. this is on line 8: let fullAuthorNames. your next line is line 12 where you again declare fullAuthorNames with const. that is the error. remove the const and it will pass.
