Tip 30: Simplify Key-Value Assignment

Explore how to rebuild JavaScript objects cleanly by using destructuring and the spread operator. Learn to assign keys with matching variable names and merge objects effectively, enhancing code clarity and maintainability.

We'll cover the following...

You just learned how to pull apart objects in a clear and clean way. Now that you have all those pieces laying out on your proverbial work bench, you need to put them back together. It wouldn’t be any good if the writers of the spec gave you a clean interface to take objects apart while leaving you no way to put them back together.

Building objects

Well, you’re in luck. The same technique you’d use to take objects apart works in reverse. It’s time to build new objects using similar syntax that will leave your code clear and predictable.

Node.js
const landscape = {
