Objects in JavaScript

Short summary

Comprehensive tutorial on JavaScript objects: creating with literal syntax, accessing/modifying properties via dot and bracket notation, defining methods, nesting objects, and using Object.keys(), Object.values(), Object.entries() for iteration. Covers Object.freeze() and Object.seal() for immutability, destructuring, and spread operator.

• •Objects store related data and methods; created with {key: value} syntax
• •Access properties via dot notation (obj.key) or bracket notation (obj['key']); modify or add dynamically
• •Use Object.keys(), Object.values(), Object.entries() to iterate; destructuring and spread operator simplify extraction
