What is the primary classification of all values in JavaScript?

The primary classification of all values in JavaScript is indeed divided into "primitive" and "object." This categorization is fundamental to understanding how data types work in the language.

Primitives are data values that are not objects and have no methods. They include types such as strings, numbers, booleans, null, undefined, and symbols. Primitives are immutable, meaning their values cannot be changed; when you manipulate them, you create a new value rather than altering the original.

On the other hand, objects are collections of properties and are more complex data structures. Objects can hold various types of data, including other objects and functions, which allows for greater flexibility and functionality. They are mutable, meaning that the properties and methods associated with an object can be changed after the object has been created.

This classification helps programmers understand how data is stored and how it behaves during operations, which is essential for writing efficient and effective JavaScript code. Thus, recognizing the distinction between primitives and objects provides a crucial foundation for further exploration of JavaScript's functionality.
