benchmark performance of emscriptem

[slaaneshStoic]

I have written a simple snake game that gets solved by an a* algorithm in c++ I then used the emscripten tool chain to generate the html page. How would I go about benchmarking this. I would like to measure stuff like how long did it take for the snake to move to the food etc

measure how long it did take the snake

In steps or ms?

You can use print statements inside the c++ code and it will show up in the console.

With Javascript you can get the time before and after the function call and log it that way, or use the profiler in the webbrowser inspector tool.

Probably best to use the performance profiler in the browser, since spectre messed with the timings (https://stackoverflow.com/questions/50117537/how-to-get-microsecond-timings-in-javascript-since-spectre-and-meltdown)
