firstInterval

Same as setInterval, but triggers immediately as well.

This pattern

callback(p1, p2);
setInterval(callback, 1000, p1, p2);

is identical to this

firstInterval(callback, 1000, p1, p2);

Installation

$ npm i --save firstInterval

Example

const firstInterval = require('./firstInterval');

console.log('starting', new Date())
const timer = firstInterval(()=>{
  console.log('interval', new Date());
}, 1000);

outputs

starting 2018-04-06T11:01:35.058Z
interval 2018-04-06T11:01:35.062Z
interval 2018-04-06T11:01:36.067Z

Test

To keep things light, there's a test, but it only logs to console.

$ npm test
