What is the impact of type checking on performance in programming?

What is the impact of type checking on performance in programming?

Type checking can significantly affect performance, especially in dynamically typed languages. It adds overhead during execution.

Can you explain how it differs between static and dynamic typing?

In static typing, type checks are done at compile time, which can optimize performance. In dynamic typing, checks occur at runtime, potentially slowing down execution.

Are there any scenarios where type checking improves performance?

Yes, in statically typed languages, type checking can lead to better optimization by the compiler, resulting in faster code execution.

What are some examples of statically typed languages?

Examples include Java, C++, and Rust. These languages perform type checking at compile time, enhancing performance.

How can I measure the performance impact of type checking in my code?

You can use profiling tools to measure execution time and memory usage, comparing versions of your code with and without type checks.
