In this chapter, we traverse the AST that was built earlier and create the methods to evaluate (or execute) the nodes according to their meaning. Another interesting feature of Raku, the so called getters, is used in the code.

In the second part of this chapter, I am talking about building the AST fragments for hosting strings, arrays, and hashes, as well as bigger constructs such as expressions, and how to manipulate these elements in a program.

An overview of the new features appeared at the Coronavirus Observer site during the first month after its launch.

In this chapter, we will be working on implementing AST, the abstract syntax tree, that represents the program in the form of connected nodes, which are responsible for atomic actions such as variable declaration, or computing a sum of two values, or calling a function. This is probably the most difficult and brain-puzzling chapters in the book.

The answer is: Accessing array or hash items with a proper sigil!

In this chapter, we will extend the Lingua language with aggregate data types: arrays and hashes. From this point, we will call variables that contain numbers and strings scalar variables.

I have written an article for perl.com about a number of interesting tricks in the Raku programming language that were used for building the Coronavirus Observer site.
