Benchmark: Promise vs Array

Tests:

Promise
let returnPromise = Promise.resolve(); for (let i = 0; i < 15; i++) { for (let j = i + 1; j <= 15; j++) { const execResult = Promise.resolve(123); returnPromise = returnPromise.then(execResult); } }
Array
let execs = []; for (let i = 0; i < 15; i++) { for (let j = i + 1; j <= 15; j++) { const execResult = Promise.resolve(123); execs.push(execResult); } } Promise.all(execs)
Nothing
for (let i = 0; i < 15; i++) { for (let j = i + 1; j <= 15; j++) { const execResult = Promise.resolve(123); } }
