  9. 9. vs. ? Missing important things Lacks full type inference ∙ No asynchronous flow No parallelism ∙ Tricky garbage collection Important things included Excellent type inference ∙ Built-in async flow Parallelism ∙ Algebraic types ∙ Units of measure More powerful pattern matching ∙ Agents One line parsing of JSON, XML, CSV Syntax support for database queries. Also, a very young language And a mature language
