# Features of Crystal
|
|
# - 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.
|
|
|
|
