# Define a hello function, 0 or 1 args:
defn hello(name='World'):
"Hello, $name!" # Return string
# Randomly call the `hello` function
# with 0 or 1 arguments:
if rand(2) > 1:
say: hello() # Print string
say:
hello: ENV.USER \"Guess user name"
.uc1() \"First char upper"
Get better at programming through fun, rewarding coding exercises that test your understanding of concepts with Exercism.
Given two buckets of different size, demonstrate how to measure an exact number of liters.
Implement the `keep` and `discard` operation on collections.
Create an implementation of the rotational cipher, also sometimes called the Caesar cipher.
Every language has its own way of doing things. YAMLScript is no different. Our mentors will help you learn to think like a YAMLScript developer and how to write idiomatic code in YAMLScript. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in YAMLScript - they'll help you discover the things you don't know that you don't know.
