An opinionated list of excellent Clojure learning materials

These resources (articles, books, and videos) are useful when you're starting to learn the language, or when you're learning a specific part of the language. This an opinionated list, no doubt. I've compiled this list from writing and teaching Clojure over the last 10 years.

Big-O Time Complexities for Elixir data structures

Map [1]

Operation	Time Complexity
Access	`O(log n)`
Search	`O(log n)`
Insertion	`O(n)` for <= 32 elements, `O(log n)` for > 32 elements [2]
Deletion	`O(n)` for <= 32 elements, `O(log n)` for > 32 elements

	A micro event loop library implementation from scratch.

	This library provides a minimal but feature-complete asynchronous event loop
	implementation for educational purposes. It demonstrates the core concepts of
	asynchronous programming including:

	- Task scheduling and management
	- I/O multiplexing with non-blocking sockets
	- Timeouts and sleep functionality

	# ActiveJob natively captures constructor arguments in an `@arguments` instance variable
	# which is also exposed as an `arguments` property on each job instance.
	#
	# Calls to `perform_now` and `perform_later` both forward arguments to the constructor.
	#
	# For example, all of these invocation styles work.
	#
	# result = DoStuffJob.new("foobar").perform # sync
	# result = DoStuffJob.new.perform("foobar") # sync
	# result = DoStuffJob.perform_now("foobar") # sync

	# This is a thin wrapper of the Simple Form builder. It delegates rendering the resulting form fields to Simple Form
	# but typically amends the Tailwind classes of the various elements in the field layout. It tightly integrates with the
	# unstyled wrapper (aka `:plain`) Simple Form configuration (see `simple_form.rb`). The methods support the same syntax
	# as the original Simple Form methods but enhance it to support replacing defaylt Tailwind claseses.
	class Builders::TailwindFormBuilder < SimpleForm::FormBuilder

	# This is the basic method for rendering `<input>` tags and their variants.
	def input(attribute_name, options = {}, &block)
	# The default Tailwind classes for the various parts of the Simple Form wrapper layout.
	input_class = "block w-full sm:text-sm ... #{'text-gray-500 bg-gray-50' if options.dig(:input_html, :disabled)}"
