How to Work with Required and Optional Keyword Arguments in Ruby 3

Ruby offers multiple ways to work with keyword arguments, including setting a list of required, named arguments, along with optional arguments. In this guide we'll walk through how to work with both options.

@@edutechional thx! I'm back at programming with Wolfram L, i.e. writing down probability theory highschool textbook problem solutions in Mathematica, incl solving them thru WL code. much fun! #studyathome. I'll upgrade to blitzstein very soon. that's college level intro.

It works in ruby 2.3 too :)

[@edutechional]

This syntax does, but Ruby 3 did introduce a few breaking changes for keyword arguments. So a few ways that worked in 2 no longer work in 3.

5:40 How do I find such an extension that evaluates expressions via commening the code? Or is it standard for Vim? Looks much better than printing everything to console. Is there one for VS Code?

[@edutechional]

It's a vim plugin that connects to the seeing is believing gem, if you're interested, I built out a full course on Vim for Ruby developers that shows how to build that (and my full setup): www.udemy.com/course/vim-training-course-ruby-developers/

email: and password: are empty default value entries of that hash?

[@edutechional]

They're not default values, they're required named arguments for the method

[@codeline9387]

it's not optional key words it's a hash

[@edutechional]

It uses the hash data structure, but it functions as a set of optional key word arguments.
