Array and Object Destructuring
Destructuring pulls values out of arrays and objects into clearly named variables. The pattern mirrors the data’s shape, which keeps repeated property access out of the surrounding code.
const coordinates = [18.07, 59.33];
const [longitude, latitude] = coordinates;
const user = { name: "Sam", role: "editor" };
const { name, role: accessLevel } = user;
console.log(name, accessLevel); // Sam editorPractice moves from skipped positions and renamed properties to defaults and destructured function parameters. Destructuring extracts values; it does not copy or update the original collection.
