Access:
1. Dot Notation (object.property)
2. Bracket Notation (object["property"])
3. Using Variables as Keys (Bracket Notation Required)
4. Optional Chaining (?.) (Avoids errors if property is missing)

2. Using Object.keys() (Loop through keys as an array)
3. Using Object.values() (Loop through values directly)
4. Using Object.entries() (Loop through key-value pairs)
5. Using forEach with Object.entries()
