@matrixai/timer

js-timer

This library provides a reified Timer replacing the imperative setTimeout in JS. This is useful for keeping track of elapsed time and calculating how time is left. Think of this as a "Stopwatch".

This does not use Date.now(), it uses Performance API.

Installation

npm install --save @matrixai/timer

Usage

import { Timer } from '@matrixai/timer';

const t1 = new Timer(() => 2, 10);
const result = await t1;
