Course of Raku / Functional, concurrent, reactive, and web programming / Functional programming / Reduction / Exercises

Comma-separated list

Problem

Using the reduce method with a block, join the words 'Raku', 'is', 'fun' into one string with ', ' between the pieces, so the result reads Raku, is, fun. The [~] metaoperator glues pieces with nothing between them, so inserting a separator is a job for a block.

Example

The program prints:

Raku, is, fun
