Benchmark: Converting a small Set to an Array

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

/* This "JavaScript preparation code" is executed just once in each run.
   Therefore, although `s` randomly generated, consistency is unaffected
   because the same object is used across all test cases below. */
const s = new Set();
for (let i = 0; i < 10; ++i) {
    s.add(Math.random());
}

Tests:

Spread operator (...)
const a = [...s];
Array.from()
const a = Array.from(s);
