Jint.Benchmark

To run tests comparing engines, use:

dotnet run -c Release --allCategories EngineComparison

Engine comparison results

• tests are run in global engine strict mode, as YantraJS always uses strict mode which improves performance
• Jint and Jint_ParsedScript shows the difference between always parsing the script source file and reusing parsed Script instance.
