javascript下利用arguments实现string.format函数

sitepoint上看到Andrew Tetlaw在08年写的文章arguments: A JavaScript Oddity，阅读之后，除了对arguments温故知新一遍以外，印象最深刻的还是Andrew的第一个函数实现的string.format功能。

This error occurs when the number of placeholders in the string formatting operation is not equal to the number of arguments passed to the format() method. For example: ``` name = "John" age = 25 print("My name is {} and I am {} years old".format(name)) ``` In this case, the string has two placeholders but only one argument is passed to the format() method. The correct way would be to pass both arguments like this: ``` print("My name is {} and I am {} years old".format(name, age)) ``` If you still get the error, check that the placeholders are correctly numbered and that the correct number of arguments are being passed to the format() method.
