 """Runs Octane 2.0 javascript benchmark.
 
 Octane 2.0 is a modern benchmark that measures a JavaScript engine's performance
 by running a suite of tests representative of today's complex and demanding web
 applications. Octane's goal is to measure the performance of JavaScript code
 found in large, real-world web applications.
 Octane 2.0 consists of 17 tests, four more than Octane v1.
