# JavaScript Rest Parameters

The rest parameter is used to represent an infinite number of arguments as an array. The rest parameter syntax is ... preceding the parameter name. This can be effect when the number of arguments is unknown, or required to be grouped together.

function add (...numbers) {
  return numbers.reduce(function (total, number) {
    return total += number
  })
}

console.log(add(4, 8, 3, 5, 2)) // 22
