What is the syntax for creating a new object in JavaScript?

The syntax for creating a new object in JavaScript involves using the new keyword followed by the Object constructor, and it is often encapsulated within variable declaration keywords such as const, let, or var to define the scope and mutability of the object.

In the correct example, a variable named obj is declared using const, indicating that the reference to the object cannot be reassigned. The new Object() part invokes the Object constructor, resulting in a newly created object. This practice is a foundational aspect of JavaScript as it allows for the instantiation of objects which can store properties and methods.

Utilizing const ensures that if the obj reference points to an object, you cannot later reassign obj to point to a different value or object, though you can still modify the properties of the object itself. This encapsulates both the creation of the object and the immutability of the variable reference, which is critical in ensuring consistent and predictable behavior in your code.

In contrast, other options may lack variable declaration or use incorrect syntax that prevents them from successfully creating a new object in JavaScript. Understanding this syntax is essential for mastering object-oriented programming in JavaScript.
