What is performance-now?

The performance-now npm package provides a high-resolution timestamp, similar to what you would get from performance.now() in a web browser. This is particularly useful for accurately measuring execution times in Node.js applications, where such precision is necessary for performance analysis and optimization.

What are performance-now's main functionalities?

High-resolution timing

This feature allows you to measure the time it takes to execute operations with high precision. The code sample demonstrates how to use performance-now to calculate the execution time of some operations in milliseconds.

const now = require('performance-now');
let start = now();
// Some time-consuming operations
let end = now();
console.log(`Execution time: ${end - start} milliseconds`);
