Randomization core extension methods.
This library extends Array, String and Hash with randomization methods. Most of the methods are of one of two kinds. Either they "pick" a random element from the reciever or they randomly "shuffle" the reciever.
The most common example is Array#shuffle, which simply randmomizes the order of an array‘s elements.
[1,2,3].shuffle #=> [2,3,1]
The other methods do similar things for their respective classes.
rand | -> | number |
alias to Kernel method rand. |
