Reusing variables?

Question

Unity

For example, I have a method

Vector2 getSomePoint(){
    return new Vector2(x,y);
}

So, instead of creating a new Vector2 object, is it better to declare one constant and change its value and then return it in order to avoid frequent calls to the garbage collector, or write as in the code above and it doesn't matter?
I myself think that it is better not to create a new object every time, but in many tutorials they do this.

Answer 1

Vector2 is a value-type, structure, it is allocated either in the memory of the aggregating object or on the stack.
new in C# doesn't mean it's a heap allocation.
Write as you wrote, everything is in order.
