Static Typing

Static typing is a programming language feature where variable types are explicitly declared and checked at compile-time, before the code runs. It enforces type safety by ensuring operations are performed on compatible data types, catching errors early in the development process. This contrasts with dynamic typing, where types are inferred or checked at runtime.

Also known as: Static Type System, Static Type Checking, Compile-time Typing, Explicit Typing, Type Safety

Why learn Static Typing?

Developers should use static typing in projects requiring high reliability, maintainability, and performance, such as large-scale enterprise applications, systems programming, or safety-critical software. It helps prevent type-related bugs, improves code documentation through explicit type annotations, and enables better tooling support like autocompletion and refactoring in IDEs.
