What are the advantages and disadvantages of using strict dynamic typing in programming languages?

Strict dynamic typing means that variable types are determined at runtime, and the language enforces type checks strictly, disallowing implicit conversions.

Advantages:

• Flexibility: no need to declare types in advance, which speeds up development.
• Convenience when working with heterogeneous data.
• Ability to write more universal and adaptive code.

Disadvantages:

• Type errors are only detected at runtime, which can lead to bugs.
• Harder to maintain and refactor large codebases.
• Lower performance compared to static typing.

For example, in Python, a variable can change its type, but if you try to perform an operation with incompatible types, a runtime error will occur.
