Crystal is a compiled language that is currently in the alpha stages of development. These are some of the language's goals:
Ruby-inspired syntax.
Statically type-checked but without having to specify the type of variables or method arguments.
Be able to call C code by writing bindings to it in Crystal.
Have compile-time evaluation and generation of code, to avoid boilerplate code.
Compile to efficient native code.
class HelloWorld
def self.hello(name = "World")
"Hello, #{name}!"
end
end
Exercism is a great website where I was able to have some very interesting challenges.
Once you join the Crystal language track, you will receive support and feedback from our team of mentors. Here are the bios of a few of the mentors of this track.
