How do I combine two arrays when the quiz program insists that using two spread operators is wrong?

Here's the quiz question:

const itemsA = [ 'Lightsaber', 'Mockingjay pin', 'Box of chocolates' ]; const itemsB = [ 'Ghost trap', 'The One Ring', 'DeLorean' ] const allItems = [ , ];

My answer: const allItems = [ ...ItemsA , ...itemsB ];

But this is wrong.

You had the right idea, but a spelling error.

Instead of "ItemsA " (with a capital I), it should be "itemsA" (camel case).

Adding to this answer - JS variables are case sensitive. A variable named Bob is not the same as one named bob
