Measure difference in performance of writeFile(string value) vs writeFile(String object)

writeFileString.js

import fs from "node:fs/promises";

// Create a 1MB string value to a file
const string = "a".repeat(1000000);
const startValue = performance.mark("string");
await fs.writeFile("1MB.txt", string);
const measureValue = performance.measure("write string value", startValue);
console.log(`${measureValue.name}: ${measureValue.duration}ms`);

// Write the string as a String object
const object = new String(string);
const startObject = performance.mark("String");
await fs.writeFile("1MBString.txt", object);
const measureObject = performance.measure("write String object", startObject);
console.log(`${measureObject.name}: ${measureObject.duration}ms`);
