Syntax and Structure of Raku Programming Language
Raku is celebrated for its clean and expressive syntax, designed to enhance readability and reduce the likelihood of errors in code. It adopts a sigil-based system for variable declaration, where the sigil denotes the type of variable. This approach makes it easy to discern variable types, promoting code clarity.
Furthermore, Raku’s syntax is consistent and coherent, emphasizing the principle of “There’s More Than One Way To Do It” (TMTOWTDI), allowing developers the flexibility to choose the most suitable approach for their coding needs. This results in elegant and legible code, fostering collaboration among developers.
Raku’s grammar, built upon a foundation of rules and regexes, enables effortless text and data manipulation, reinforcing its status as a language with a versatile and adaptive structure.
Example
| # Variable Declaration my $name = “John”; # $ denotes a scalar variable my @numbers = 1, 2, 3; # @ denotes an array my %person = “name” => “John”, “age” => 30; # % denotes a hash # Control Structures if $age >= 18 { say “You are an adult.”; } else { say “You are a minor.”; } for @numbers -> $num { say “Number: $num”; } # Subroutine Declaration sub greet($name) { say “Hello, $name!”; } greet(“Alice”); # Regular Expression if “Raku is amazing” ~~ /amazing/ { say “Found ‘amazing’ in the string!”; } # Object-Oriented Programming class Person { has $.name; has Int $.age; method say_hello { say “Hello, my name is $.name, and I am $.age years old.”; } } my $person = Person.new(name => “Alice”, age => 25); $person.say_hello(); |
