// If you use Node / CommonJS / not a ES2015 module compiler
const Timer = require('timerize').default;

// If you use TypeScript / a ES2015 module-compatible navigator/compiler
import Timer from 'timerize';


const timer = new Timer;

console.log(timer.elapsed); // 12 for exemple

// Change the format of number output
timer.format = "s";

console.log(timer.elapsed); // 1.123 for exemple

// Change the default format for every new Timer instances and instance with unchanged format
Timer.default_format = "s";

timer.pause();

// do things

timer.start();

// ...

Important note:

The timer does not consume any resource when it is "running". Calculations are made when you get the elapsed time.

You can leave him without call pause() and waiting for it became garbage-collected.
