Node JS file write time [duplicate]

Question

I have code that writes data to a file, how can it be done to show how much time it took to write a file?

const fs = require("fs");
fs.writeFile('./text.json', JSON.stringify(m), (err) => {
    if (err) console.log(err);
});

Answer 1

you can do something like this:

/*

time from unix epoch in milliseconds = new Date().getTime();

*/


const currentTime = new Date().getTime();

// Some operation here

const timeNow = new Date().getTime();

const timeTookInMilliseconds = timeNow - currentTime;
