Static typing determines and checks variable types before execution, during compilation. The compiler enforces type constraints and prevents programs with unresolved or conflicting types from proceeding. section 1.2.2
Static typing supports backend and infrastructure development by providing:
- Compile-time verification that variables satisfy their type constraints. section 1.2.2
- Type inference when a variable’s type is not explicitly specified. section 1.2.2
- Helpful compiler errors when inference fails or type constraints conflict. section 1.2.2
- Earlier detection of an entire class of runtime errors. section 1.2.2
Inference and conflicts
A variable without an explicit type can still compile when the compiler infers its type. If available information is insufficient or constraints conflict, compilation stops with an error. section 1.2.2
