Ice Cream Quantity explainer


#1

The aim of this puzzle: Use the .length property to count the number of elements in an array

Walkthrough of the solution: The length property is used to count the number of elements contained in an array. For example:

console.log(['cat', 'dog', 'rabbit'].length)

will print 3, as there are 3 elements in the array.

In this puzzle, the listOfIceCreams array is imported from additional code.

On the next line, the numberOfFlavors variable is declared. As we can tell from its name, this variable should hold the number of flavors contained in listOfIceCreams.

To complete the puzzle, add .length to the end of listOfIceCreams, so the number of elements in the array is saved to numberOfFlavors.

Sample code solution:
(Tap below to reveal)

import { listOfIceCreams } from 'grasshopper.treats';

let numberOfFlavors = listOfIceCreams.length;

console.log('There are ' + numberOfFlavors + ' flavors to choose from');
