Js Objects Destructuring in Javascript
JavaScript objects store key-value pairs. You can read, add, update, and delete properties. Methods are functions stored as properties.
Destructuring extracts values from objects or arrays into variables: const { name, age } = student instead of student.name, student.age.
Spread operator (...) copies all properties of an object: const updated = { ...student, age: 16 } creates a new object with one property changed.
Optional chaining (?.) safely accesses nested properties: user?.address?.city — returns undefined if any part is null/undefined instead of throwing an error.
