JavaScript is Object-Based rather than fully Object-Oriented because:

Object-Based Language

• JavaScript uses objects extensively but does not support features like class-based inheritance (before ES6 introduced class syntax).
• It follows prototype-based inheritance rather than classical OOP (Object-Oriented Programming).

Why Not Other Options?

• (B) Assembly-language → ❌ Incorrect, because JavaScript is a high-level language, not low-level like Assembly.
• (C) High-level → ✅ JavaScript is a high-level language, but the most precise classification is "Object-Based."
• (D) Object-Oriented → ❌ JavaScript does have OOP features (like objects and prototypes), but it lacks true class-based OOP principles like Java or C++.

Thus, JavaScript is primarily "Object-Based" because it uses objects but not full OOP features.
