Type Inference
Deduces expression types from rules and usage instead of explicit annotations
Why learn Type Inference?
It preserves static checking with less repetitive syntax
The problem it solves
It derives type information that programmers did not write directly
Where it came from
Type Inference is a programming language and runtime concept that deduces expression types from rules and usage instead of explicit annotations. Its guarantees and tradeoffs depend on the concrete implementation and operating context.
