Array: getElementsByClassName(["c1", "c2"]);
Varargs: getElementsByClassName("c1", "c2");
In the first case, there are just two more characters, but this method has two advantages that can't be ignored:
1. All languages have arrays, but not all languages support varargs.
2. It's easy to call the array version with an array that's constructed dynamically, without knowing the number of items in advance. Not all languages even with varargs support allow you to call a varargs function like that.
