Join Together explainer


#1

The aim of this puzzle: Combine the items in the saleItems array into a single string.

Walkthrough of the solution: The starter code already attaches the elements together using .join(). The argument is 'GLUE' is being inserted between each string. You can change that string to something else, like ' & ' to match the solution.

The .join() method returns a new string, and it won’t affect the original array.

Sample code solution:
(Tap below to reveal)

let saleItems = ['Bug Bites', 'String Beans', 'Console Lager'];
console.log('For sale: ' + saleItems.join(' & '));

JavaScript Concepts: Binary Expression (+ concatenation), console.log(), .join()
