I can't get the answer to this quiz question.

Say you have two arrays, itemsA and itemsB, and you want to combine them into a new array named allItems. Complete the code so that the new allItems array stores the elements from itemsA first, followed by the elements inside itemsB:

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

Im supposed to fill in the last gap in the allitems array but i haven't got a clue.

You can create an expression that represents all the elements of an array by preceeding the array name with the spread operator.
