Objects

An object groups related values under named keys: { title: "Dune", year: 1965 } instead of three separate loose variables. You read a property back with dot notation - book.title - and it reads almost like English.

Template literals (backticks instead of quotes) let you drop a variable or expression straight into a string with ${...}, instead of gluing pieces together with +. Combine the two and you can build a display string directly out of an object's properties, so it stays correct even if the object's values change later.

Your task: create an object book with title ("Dune"), author ("Frank Herbert"), and year (1965). Then build summary, a string reading "Dune by Frank Herbert (1965)", out of those properties.

You'll practice:

Creating an object literal
Reading properties with dot notation
Building a string with a template literal

// Create an object called book with title, author, and year.
const book = {

};

// Then create summary: "<title> by <author> (<year>)"
const summary = "";
