 # Phlex vs Slim
+
+[Slim](https://slim-template.github.io)’s goal is reduce templating syntax to just the essential parts without becoming cryptic.
+
+We can’t really make a direct comparison between Phlex and Slim becuase Slim is not a component framework and Phlex is not a templating language. However, there are some similarities between the two that we can look at. We can also get into why Phlex is designed around this idea of a “component”.
+
+### Minimal templating syntax
+
+If you’re using Slim, there’s a good chance you wanted something with a more minimal syntax than ERB, especially when it comes to switching between the HTML parts and the Ruby parts, such as an `if` conditional.
+
+Phlex too has a pretty minimal syntax, with one significant difference: the Phlex syntax is just Ruby. You don’t need to learn anything else, you already know it. Modules, classes, methods, arguments, blocks. That’s it.
+
+Because it’s just Ruby, the transition between the Ruby code and the template code is even more seamless. There’s no transition because it’s all Ruby. One factor to consider is Ruby doesn’t have significant whitespace.
+
+### Components and abstraction
+
+Phlex is designed around the idea of a “component”. A component is a Ruby class that represents a small part of the page. Extracting small components helps keep your user experience consistent and makes your code much easier to maintain in the long run.
+
+Additionally, because Phlex is just Ruby, you can start by extracting methods.
+
+```ruby
+def MyButton(...)
+  button(class: "my button classes", ...)
+end
+```
+
+When you realise you need more options, you can upgrade that to a class.
+
+```ruby
+class MyButton < ApplicationComponent
+  def initialize(style:, color:)
+    @style = style
+    @color = color
+  end
+
+  def view_template(&)
+    button(class: [@style, @color], &)
+  end
+end
+```

 ## Attribute values
 
-You’ve seen how string values work. Symbols behave the same way. You’ve also seen how to nest attributes with hashes. But Phlex allows a few other types of attribute value.
+### Symbols
+
+Like keys, if you use symbols for values, Phlex will convert them to strings, replacing underscores `_` with dashes `-`.
+
+::: code-group

+```ruby [component]
+div(contenteditable: :plaintext_only)
+```

-Some HTML attributes such as `contenteditable` require you to pass `"true"` or `"false"` as a string. These are not technically “boolean” attributes, they're “enumerated” attributes. The distinction is subtle but important.
+Some HTML attributes such as `contenteditable` require you to pass `"true"` or `"false"` as strings. These are not really _boolean_ attributes even though they look similar; they’re technically _“enumerated”_ attributes.
+
+According to [the MDN Web Docs](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/contenteditable), `contenteditable` accepts `"true"`, `"false"` or `"plaintext-only"`. The presence of this third option explains why `contenteditable` is not a boolean attribute. It also means new modes could be added in the future without breaking existing code.

+
 In this example, the `button` class is always added, while the `active` and `disabled` classes are conditional. You can read `=>` as “if”.
 
+Phlex also ignores `nil` values, so another way you could write this is:
+
+```ruby
+a(
+  class: [
+    ("button"),
+    ("active" if is_active),
+    ("disabled" if is_disabled)
+  ]
+) { "Click me" }
+```
+
+The parentheses around `"button"` here are not strictly necessary because it’s not paired with a conditional, but they make the code more consistent. Also, this last technique works for any attribute, not just `class`.
+
 ### `style`
 
 Like `class`, the `style` attribute has special behaviour. If you pass a Hash to `style`, Phlex will convert it to a CSS string:
