What are Object constructors in JavaScript ?
When you use Object(value) as a function (without the new keyword), you are using the Object Constructor as a Type Transformer.
The Object() constructor turns the input into an object. Its behavior depends on the input's type.
If the value is null or undefined, it creates and returns an empty object.
If the value is an object already, it returns the value.
Otherwise, it returns an object of a type that corresponds to the given value. For example, passing a BigInt primitive returns a BigInt wrapper object
Ensuring an Input is Object-Safe: If you are writing a function that expects an object but might receive null, calling Object() on the input prevents your code from crashing when you try to access properties.
Coercing Primitives to Objects: Sometimes you need a primitive to behave like an object permanently (not just via temporary autoboxing).
Checking if a value is already an object: Since Object(value) returns the same reference if the input is already an object, you can use it for identity checks.
