How do you conduct JavaScript speed tests for performance testing JavaScript code?

2

One simple way to conduct JavaScript speed tests is to use the performance.now() method, which provides high-resolution time stamps. You can measure execution time by capturing timestamps before and after the code execution:

const start = performance.now();

// Your JavaScript code here
for (let i = 0; i < 1e6; i++) {
    Math.sqrt(i);
}

const end = performance.now();
console.log(`Execution time: ${end - start} milliseconds`);

This method allows you to quantify the execution time and assess the performance of different code snippets effectively.
