Aim of the puzzle: Use the .pop() array method to remove an item from the end of an array.
Walk through of solution: Using the .pop() array method on an array will remove the last item from the array and return it. Because the item is returned, it can be saved to a variable.
In this puzzle, the variable bookShelf is imported from additional code. This variable contains the following array of strings:
[
'Harry Potter and the Sourcerer\'s Stone',
'Tinker Tailor Soldier Spy',
'Portrait of the Artist as a Young Man',
'Eloquent JavaScript',
'Grace Hopper: Admiral of the Cyber Sea'
]
The second line of code uses .pop() to remove the last item from the bookShelf and save it to the variable bookOne.
To complete the puzzle, add .pop() to the end of let bookTwo = bookShelf. Then use console.log() to print bookTwo to the console.
Sample code solution:
import { bookShelf } from 'grasshopper.books';
let bookOne = bookShelf.pop();
let bookTwo = bookShelf.pop();
console.log(bookOne);
console.log(bookTwo);
