 * Using curly braces on the left of an assignment,

 *

 * { name1, name2 } = myObject;

 *

 * assigns property values of the object on the right

 * to variables with matching names.

 *

 * The process is called object destructuring

 *

 * 1) Assign the published property to a matching variable.

 *

 * 2) Include the new variable in the template.

 *

 * The destructured variables are declared as constants.

 *

 * 4) Add a second book and try the destructuring

 *    process again.
