* Each input is parsed |RUNS| times and the results are averaged. We do
|
|
* this for two reasons:
|
|
*
|
|
* 1. To warm up the interpreter (PEG.js-generated parsers will be most
|
|
* likely used repeatedly, so it makes sense to measure performance
|
|
* after warming up).
|
|
*
|
|
* 2. To minimize random errors.
