JavaScript Objects: A Developer's Guide 💻

JavaScript objects are fundamental to the language, serving as containers for key-value pairs and enabling complex data structures. Here's a breakdown of core concepts:

📌 Basic Concepts

• Object Literals: Define objects using curly braces {}
  Example:

  const user = { name: "Alice", age: 25 };
  

• Properties & Methods: Store data (properties) and functions (methods)

  user.greet = function() { return "Hello!"; };
  

• Prototypal Inheritance: Objects inherit properties from prototypes (e.g., Object.create())

🔍 Common Use Cases

• Data Modeling: Represent real-world entities

  const car = { make: "Tesla", model: "Model S", year: 2023 };
  

• APIs: Store configuration or state

  const config = { endpoint: "/api/data", timeout: 5000 };
  

• Functions as Objects: Methods can be assigned or modified dynamically

🧠 Best Practices

1. Use const or let to declare objects
2. Prefer object literals for simple structures
3. Avoid eval() when working with object data
4. Leverage Object.keys()/Object.values() for iteration
