Benchmark: for loops vs forEach test: call functions from Map() value iterator with 4 items

Script Preparation code:

 var functions = [
    () => Math.random() + 10,
    () => Math.sqrt(Math.random() * 100),
    () => Math.floor(Math.random() * 50),
    () => Math.pow(Math.random(), 2),
];
var functionsMap = new Map();
functions.forEach((fn, i) => functionsMap.set(i, fn));

Tests:

for...of
for (const fun of functionsMap.values()) fun();
forEach
functionsMap.values().forEach(fun => fun());
