Let's picture this part of it [firstElement, secondElement, thirdElement] to be an array. If this were an array, firstElement would be at position 0 of the array. JavaScript will see that this firstElement variable is at position 0, then it will go into the animals array and find the element that's at position 0, and assign that element to the variable firstElement.

Because variables are mapped to values in the array by position, destructuring syntax can be used to assign or re-assign multiple variables in a single expression.
