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
