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 = {};
functions.forEach((fn, i) => functionsMap[i+""] = fn);

Tests:

for...of
const values = Object.values(functionsMap); for (const fun of values) fun();
forEach
const values = Object.values(functionsMap); values.forEach(fun => fun());
for (C style)
const values = Object.values(functionsMap); for (let i = 0; i < values.length; i++) values[i]();
