CS111: Data Types - Objects (JSON)

Using object literals and JSON for configuration

Data Types: Objects (JSON)

Objective

Students must use object literals and JSON notation to structure and store complex data.

Evidence

Object and JSON usage in game components:

GameLevelOutside.js - Configuration objects with game settings
GameLevelMaze.js - Maze layout objects
Multiple classes - Game entity data structures

Implementation Details

Object literal notation with key-value pairs
Accessing properties with dot notation and bracket notation
JSON format for data representation
Nested objects for hierarchical data
Object methods and properties

Key Concepts

Object literals: { key: value }
Property access: dot notation vs bracket notation
JSON format and JSON methods (parse, stringify)
Object methods: Object.keys, Object.values, Object.entries
Destructuring for extracting properties
