第一个参数可以通过param1形参获取到,或者使用arguments[0]的形式。但是第二个参数只能通过arguments[1]的方式获取到了。arguments获取实参的方式可以和形参一起使用。 arguments对象包含了传入函数的每一个实参,第一个实参从arguments的第一位开始。如果我们想获得后面的值,则可以通过角标方式读取,比如arguments[2],argu...
原文地址:how-to-use-arguments-and-parameters-in-ecmascript-6 ES6是最新版本的ECMAScript标准,而且显著的改善了JS里的参数处理。我们现在可以在函数里使用rest参数、默认值,结构赋值,等等语法 在这个教程里,我们将会仔细的探索实参和形参,看看ES6是如何升级他们的。
The parameters, in a function call, are the function's arguments.JavaScript arguments are passed by value: The function only gets to know the values, not the argument's locations.If a function changes an argument's value, it does not change the parameter's original value....

Note that when you are working with multiple parameters, the method call must have the same number of arguments as there are parameters, and the arguments must be passed in the same order.A Method with If...ElseIt is common to use if...else statements inside methods:...
