??演算子(null合体演算子)が便利すぎる

NullCoalescingOperator.cs

void Awake()
{
    BoxCollider boxCollider = GetComponent<BoxCollider>();
    if (boxCollider == null)
    {
        boxCollider = gameObject.AddComponent<BoxCollider>();
    }
}


// ===== ↑今ままで / ??演算子を使い始めたら↓  =====

void Awake()
{
    BoxCollider boxCollider = GetComponent<BoxCollider>() ?? gameObject.AddComponent<BoxCollider>();
}
