TODO: Ensure embedding this will embed the actual docs in my markdown renderer. I guess it might already do so!

TODO: It would be great to learn more about this topic and see if I can make more cross-environment packages. A great use case would be to create a wrapper around the current fs-orm to enable using it at the frontend too.

getNewPerformance()

Function that lets you measure performance inside any function with ease.

Usage:

Firstly, make a performance array, and a unique execution id, and start the measurement, like so:

import { generateUniqueId, getNewPerformance, PerformanceItem, cleanupTimer } from "measure-performance";

at the start of your function

const executionId = generateUniqueId();
const performance: (PerformanceItem | undefined)[] = [];
getNewPerformance("start", executionId, true)

After that, push a new performance item at every step you want to measure. Provide your label describing what happened before this (the step you are measuring).

performance.push(getNewPerformance("your label", executionId));

At the end of your function, you can view your performance array by printing it on the console (or store it somewhere if you like)

Don't forget to run
