Example 1:

\n\n
\nInput: argsArr = [5]\nOutput: 1\nExplanation:\nargumentsLength(5); // 1\n\nOne value was passed to the function so it should return 1.\n

Example 2:

\n\n
\nInput: argsArr = [{}, null, "3"]\nOutput: 3\nExplanation: \nargumentsLength({}, null, "3"); // 3\n\nThree values were passed to the function so it should return 3.\n

示例 1：

\n\n
\n输入：argsArr = [5]\n输出：1\n解释：\nargumentsLength(5); // 1\n\n只传递了一个值给函数，因此它应返回 1。\n
\n\n

示例 2：

\n\n
\n输入：argsArr = [{}, null, \"3\"]\n输出：3\n解释：\nargumentsLength({}, null, \"3\"); // 3\n\n传递了三个值给函数，因此它应返回 3。\n
