Ref vs Value quiz

Question

For the previous example, why we weren’t able to modify the length of the array but we could modify the content?

	a was declared as a static array, hence it’s length can’t be modified	a contains a length property - a number, and a pointer to data. For both functions a copy of a was created and, at the end of each function, the actual length and pointer were not modified. For the actual data, we are able to modify it as long as we have a reference to it.
	When we tried to modify the length the array was passed by value, when we modified the actual data the array was passed by reference	a contains a length property - a number, and a pointer to data. For both functions a copy of a was created and, at the end of each function, the actual length and pointer were not modified. For the actual data, we are able to modify it as long as we have a reference to it.
	The data was not modified, a new array was allocated and the reference was changed.	a contains a length property - a number, and a pointer to data. For both functions a copy of a was created and, at the end of each function, the actual length and pointer were not modified. For the actual data, we are able to modify it as long as we have a reference to it
	The length was not modified because the array was passed by value, but the data can be modified because we don’t change the reference to it.	Correct!
