Class Timer

Utility class for measuring and tracking elapsed time.

The Timer class provides functionality to measure elapsed time with millisecond precision. It can be started, stopped, and reset, and supports different formatting options when converting to a string representation.

Example

// Create and start a new timer
const timer = new Timer();

// Do some work...

// Get the elapsed time
console.log(`Operation took ${timer.elapsed}ms`);

// Stop the timer
timer.stop();

// Convert to formatted string
console.log(timer.toString('seconds')); // e.g., "2.5s"

// Reset and reuse
timer.reset();
Copy

The Timer instance can be used directly in string contexts or arithmetic operations through its implementation of Symbol.toPrimitive.
