How do I use d8 to benchmark my code?

[janryWang]

I want to simply test the performance of my javascript code in the latest v8 engine, but I don't want to upgrade nodejs frequently, because some libraries involved may not be compatible with the latest version of nodejs, and it is also possible that nodejs will not upgrade the v8 engine frequently. will be too high, so the problem I am facing now is how to combine ios-bench with d8
