When using the spread operator on an array, the correct output showcases the contents of that array as a new array structure. In this case, if you have an array like [1, 2, 3] and apply the spread operator, it effectively expands this array into its individual elements, resulting in a new array that retains the original structure.

This means that when you log the array using the spread operator, you'll see it represented exactly as it is: [1, 2, 3]. This behavior highlights the efficiency and simplicity of using the spread operator, which allows developers to easily manipulate and expand arrays or iterable objects.

The alternative choices do not accurately reflect the output of the spread operator applied to an array. For example, the choice with individual elements logged as 1, 2, 3 would indicate elements being listed without array structure, which is not how the spread operator is typically used in this context. Each option presents a different interpretation of how the spread operator might behave, but only the choice representing it as a new array accurately portrays the correct output generated when logging an array wrapped in the spread operator.
