Timing & Benchmarks

Measure performance and control async timing

index.ts

import { sleep, benchmark, Stopwatch, debounce, throttle } from 'ts-time-utils/performance';

// Sleep/delay
async function demo() {
  console.log('Starting...');
  await sleep(1000); // Wait 1 second
  console.log('Done!');
}

// Benchmark a function
async function benchmarkDemo() {
  const results = await benchmark(() => {
    // Heavy operation
    Array.from({ length: 10000 }, (_, i) => i * 2);
  }, 100); // Run 100 times

  console.log(`Average: ${results.average.toFixed(2)}ms`);
  console.log(`Min: ${results.min.toFixed(2)}ms`);
  console.log(`Max: ${results.max.toFixed(2)}ms`);
}

// Stopwatch for manual timing
const stopwatch = new Stopwatch();
stopwatch.start();
// ... do some work ...
stopwatch.pause();
console.log('Paused?', stopwatch.isPaused());
stopwatch.resume();
console.log('Elapsed:', stopwatch.getElapsed(), 'ms');
console.log('Stopped at:', stopwatch.stop(), 'ms');

// Debounce (wait until calls stop)
const debouncedSave = debounce((data) => {
  console.log('Saving:', data);
}, 300);

// Throttle (max once per interval)
const throttledLog = throttle((msg) => {
  console.log(msg);
}, 1000);
