javascript function typed parameters code example

Example 1: javascript function variable arguments

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

foo(1,2,3);
//1
//2
//3

Example 2: js use param object or multiple

Like many of the others, I often prefer passing an options object to
a function instead of passing a long list of parameters, but it
really depends on the exact context.

I use code readability as the litmus test.
