Ruby on Rails: The Documentary [video]

[flagged]

Just a guess -- probably the ones mentioned such as dropping webpacker, typescript

I can appreciate that. There's a few revelations I've had over the years of learning Ruby that highlighted "why things are as they are". Decisions that feel arbitrary and against the grain, but actually make a lot of sense when you understand the design as a whole. And I don't mean to imply "You just need to understand the roots, man!". It's probably the reason people who like Ruby are zealous about it, and many aren't. It's all about that Ruby brain glove.

Two great examples that everyone comes into right away are "Why are parenthesis optional? Why do you not have to `return`? Why do you allow such chaos to run abound willy nilly?!".

It isn't because "We just like being different!" or "We are allergic to parenthesis!". It turns out that one of the fundamental designs of the language makes it such that they don't really _mean_ anything.

I think being able to understand some of that context is really valuable to "ruby making sense" vs not. You often see people proclaim "In Ruby, everything is an object!" And it doesn't make much sense why that's a big deal. But the ramifications are actually amazing: Everything (basically) is an object -- even stuff that feels deep in the guts of the core of the language (defining a class for example). It turns out, this creates an amazing amount of _consistency_ where every single thing in Ruby from my app code, down to the low level parts of the language follow the same rules. This then makes it easy to anticipate how something works, or find out more about it.

I don't expect to single handedly fit your Ruby gloves to your brain, but here are some notes that define Ruby that I find enlightening:

- (Pretty much) Everything is an object. A `thing` is an object. A literal `1` is an object. A `class Mom; ... ; end` is an object. They all follow the same rules. If you want to learn what you can do with an object, you just need to learn what kind of object it is, and then you can find out what it knows. There aren't top-level functions to act on your objects. Ruby is all about "passing messages to objects". Your object knows how to handle itself.

- Things that look like operators are just methods on those objects. `thing > other` is calling the `.>(other)` method on `thing`. Accessing data from an object always happens via a method. There's no such thing as "accessing a property vs calling a method". It's all calling a method, always. This adds to the consistency.

- (Pretty much) Everything is an expression. A value is already created and stored in memory somewhere; might as well make it available to the next fellow. This enhances the ability to ... _express_ (sorry) things. You can expect to be able to chain things together, or leverage values as they are created.

- The whole motif surrounds having a conversation with your objects. It's less about making statements to your computer, and more about having a conversation with the context you are working in.

Honestly, these are all common bullet points that people bring up, but to me they didn't make much sense until I really held a strong grasp of the language as a whole. At some point, those bullet points became my "woah" moment of _why_ Ruby is how it is. This understanding in how Ruby was different from other languages I've used helped me understand why Ruby fits my brain like a glove. This style of creating makes a lot of sense to me.

Well anyway, thanks for staying for dinner.
