Type checking Meaning

Type checking is the process of verifying and enforcing the constraints of data types within a program. In statically typed languages, such as Java or C++, type checking occurs at compile time, ensuring that variables and function parameters adhere to declared types and catching type-related errors before the program runs.

Dynamically typed languages, like Python or JavaScript, perform type checking at runtime, offering flexibility but increasing the risk of runtime errors. In smart contract development, type checking is crucial for preventing bugs and vulnerabilities: ensuring that numeric values do not overflow, addresses conform to expected formats, and functions receive valid inputs.

Strong type systems can improve code safety and maintainability by catching mistakes early, while unit tests and static analysis tools complement type checking to provide additional assurance.
