ExBenchmark

Benchmarking various implementations in Elixir.

Usage

Check for emptiness: Enum.empty?/1 vs Enum.count/1 vs equality comparison (== [] and == %{})
Prepend one item to list: ++ vs Enum.concat/2 vs [elem | list]
Concatenate two lists: ++ vs Enum.concat/2 vs Enum.reduce/3 with [elem | list]
Delta two lists: one -- (one -- two) vs MapSet.intersection/2
Simple string matching: Regex.match? vs String.contains?/2, String.ends_with?/2, String.equivalent?/2, String.starts_with?/2
Retrieving key-value: Map.get/3 vs Keyword.get/3
Dropping key-value: Map.drop/2 vs Keyword.drop/2
Inserting key-value: Map.put/2 vs Keyword.put/2
Accessing a map: Map.get/3, Map.fetch/2, Access.get/3 vs pattern matching (https://medium.com/learn-elixir/speed-up-data-access-in-elixir-842617030514)
Split a string by position: binary pattern matching vs String.split_at/2
