What are the best practices for measuring execution time in programming?
To measure execution time effectively, you should use high-resolution timers, avoid including setup time, and run multiple iterations.
Can you recommend any specific tools or libraries for this?
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 ensure my measurements are accurate?
To ensure accuracy, run your code multiple times, average the results, and avoid measuring in a busy environment to reduce noise.
What common mistakes should I avoid?
Common mistakes include measuring the wrong section of code, not accounting for warm-up time, and failing to consider external factors like system load.
