for(let i = 0; i < 1000000; i++) {
  // Some operation
}
console.timeEnd('loop');

Basic execution time measurement
This demonstrates basic execution time measurement: 1) console.time() creates a named timer, 2) Precise timing measurements for specific code blocks, 3) Useful for quick performance comparisons, 4) Built-in way to profile code execution time, 5) No external tools required, 6) Can be used with multiple timers simultaneously, 7) Provides millisecond precision timing, 8) Helpful for identifying slow operations in development.
