Map vs Array

Benchmark created on March 14, 2023

Setup

const envsArr = new Array(1000).map(i => date.now()).map(n => ({name: n + '', stage: n % 2 === 0 ? 'alpha' : 'beta'}));


const envsMap = envsArr.reduce((acc, env) => {
	acc[env.name] = {stage: env.stage};
	
	return acc;
}, {});


const createNameForEnv = (input) => `${input.name}-${input.stage}`;

const createEnvs = (envs) => envs.forEach(env => createNameForEnv(env));


const createNameForEnv2 = (envName, env) => `${envName}-${env.stage}`;

const createEnvs2 = (envs) => Object.keys(envs).forEach(key => createNameForEnv2(key, envs[key]));

Test runner

const arr = createEnvs(envsArr);

const map = createEnvs2(envsMap);
