Combine multiple objects
Spread multiple objects to merge them. Properties from later objects override earlier ones.
const defaults = { theme: "light", lang: "en" };
const userPrefs = { theme: "dark" };
const settings = { ...defaults, ...userPrefs };
// { theme: "dark", lang: "en" }
This pattern is common for applying user settings over defaults.
