How to reverse an array in Javascript?

Question

Some of you may know the method in Ruby that allows you to reverse an array:

arr = ['a', 'b', 'c']
puts arr.reverse

#=> ['c', 'b', 'a']

How would one write a function (or prototype if you wish) in Javascript?

Answer 1

A quick glance at the array page in the manual shows a reverse method

> arr = ['a', 'b', 'c']; arr.reverse(); console.log(arr);
[ 'c', 'b', 'a' ]
