javascript - JavaScript可变参数个数(JavaScript variable number of arguments to function)

Is there a way to allow "unlimited" vars for a function in JavaScript?(有没有办法允许JavaScript中的函数使用“无限”的var?)

Example:(例:)

load(var1, var2, var3, var4, var5, etc...)
load(var1)

Sure, just use the arguments object.(当然,只需使用arguments对象。)

function foo() {
  for (var i = 0; i < arguments.length; i++) {
    console.log(arguments[i]);
  }
}
