Benchmark: casa - for...of vs Array.from vs .forEach

Script Preparation code:

var searchParams = new URLSearchParams(new Array(100).fill({
    key: 'foo',
    value: 'bar'
}).map(({
    key,
    value
}) => [key, value].join("=")).join("&"))

Tests:

Array.from
const queryParameters = Array.from(searchParams) .filter(([key, value]) => key && value) .map(([key, value]) => ({ key, value }));
forEach
const queryParameters = []; searchParams.forEach((value, key) => { if (key && value) { queryParameters.push({ key, value }); } });
for...of
const queryParameters = []; for (const [key, value] of searchParams.entries()) { if (key && value) { queryParameters.push({ key, value }); } }
