Javascript Performance Test
There are several ways to test the performance of JavaScript code. Here are a few options:
1. console.time() and console.timeEnd(): These methods can be used to measure the time it takes for a block of code to execute. For example:
|
2 3 4 5 |
const start = performance.now(); // code to be tested goes here const end = performance.now(); const duration = end - start; |
2. performance.now(): This method returns a high-resolution timestamp that can be used to measure the duration of an operation. For example:
|
2 3 4 5 |
const start = performance.now(); // code to be tested goes here const end = performance.now(); const duration = end - start; |
3. window.requestAnimationFrame(): This method can be used to measure the time it takes to render a frame in the browser. It is often used to benchmark the performance of graphical applications.
4. Benchmarking libraries: There are also several libraries that can be used to automate the process of benchmarking JavaScript code. Some popular options include Benchmark.js, jsPerf, and SpeedCurve.
It’s important to keep in mind that performance can vary based on the hardware and software configuration of the system running the code. Therefore, it’s generally a good idea to test performance on a representative sample of devices and environments.
