What are the best practices for timing code execution?

To effectively time code execution, you should use high-resolution timers, avoid including I/O operations, and run multiple iterations.

Can you recommend any specific tools or libraries for timing?

Sure! For Python, you can use the time module or timeit for more accurate measurements. In JavaScript, console.time() and performance.now() are great options.

How do I interpret the results from these tools?

Look for the average execution time over multiple runs to get a reliable measurement. Also, consider the variance to understand consistency.

What common mistakes should I avoid when timing my code?

Avoid timing code that includes user input or network calls, as they can introduce variability. Also, don't forget to warm up your code before measuring.
