I'm writing some unit tests using mocha and want to do a micro benchmark around a piece of code

Something like this

const startTime = getTime();
doOperations();
const endTime = getTime();
console.log(startTime - endTime);

is this possible in Javascript / nodejs / mocha?

I'd like to run this in my test environment just to check speed of some critical operations on nodejs server side

For browser

Use performance.measure() API

For Node.js

Use similar performance.measure API

For just console logging , you could use console.time API alongwith console.timeLog and console.timeEnd
