Profiling JavaScript Code

Sampling profilers are designed for low overhead: 1) Take periodic snapshots instead of tracking every function call, 2) Minimal impact on application performance, 3) Provide statistical view of performance, 4) Better suited for production environments, 5) Less detailed but more practical for continuous use, 6) Good balance of insight and overhead, 7) Can run longer without significant impact, 8) Ideal for monitoring production applications.
