random

Inspired by Python's Standard Library random module.

random = require('./random')

# Randomly selected sample number.
array = [0..10]
random.choice(array)

# A number randomly chosen between 0 and 2.
random.randrange(2)

# A number randomly chosen between 2 and 5.
random.randrange(2, 5)

# Randomly chosen 2, 4, or 6.
random.randrange(2, 6, 2)

# Randomly chosen number between 2 and 5.
random.randint(2, 5)

# Single random sample number. Same as choice.
array = [0..10]
random.sample(array)

# Array of two randomly sampled numbers.
array = [0..10]
random.sample(array, 2)

# Returns a randomly shuffled array.
array = [0..10]
random.shuffle(array)
