What is an attribute of a strongly typed language?

A strongly typed language is one that enforces strict type rules throughout its operations. This means that the language requires explicit declarations of variable types and does not allow operations to be performed on mismatched types without a clear and explicit conversion. This attribute helps to prevent type-related errors at compile time, ensuring that type safety is maintained and that programs behave predictably.

By enforcing strict type rules, strongly typed languages promote clearer code and can help programmers catch mistakes early in the development process. As a result, this characteristic is significant in enhancing the reliability and maintainability of the code, as well as improving collaboration among developers who need to understand how data is structured within the program.

In contrast, some languages might permit implicit type conversion, allow for more flexibility in assigning types, or even not require type declarations at all; these attributes do not align with the defining features of a strongly typed language.
