What's the JavaScript equivalent of Ruby's splat operator?

In Ruby, you can use the splat (*) operator to capture a variable number of arguments to a function, or to send the contents of an array to a function as an argument, like so:

def example(arg1, *more_args)
  puts "Argument 1: #{arg1.inspect}"
  puts "Other arguments: #{more_args.inspect}"
end

test_args = [1, 2, 3]

example(*test_args)

Output:

Argument 1: 1
Other arguments: [2, 3]

What's the equivalent of this in JavaScript?
