Quick Reference Card

Object Operations

// Create
const obj = { name: 'Alice', age: 30 };

// Access
obj.name;           // Dot notation
obj['name'];        // Bracket notation
obj?.address?.city; // Optional chaining

// Modify
obj.email = '[e-mail]';       // Add/update
delete obj.age;              // Remove
const { name, ...rest } = obj; // Destructure

Object Methods

Object.keys(obj);       // ['name', 'age']
Object.values(obj);     // ['Alice', 30]
Object.entries(obj);    // [['name','Alice'], ['age',30]]
Object.fromEntries(entries);  // Reverse

Object.assign({}, a, b);  // Shallow merge
{ ...a, ...b };           // Spread merge (preferred)

Object.freeze(obj);       // Immutable
Object.seal(obj);         // No add/delete
