Simple exponential backoff because the others seem to have weird abstractions.

It's based on backo2, The difference is as follows.

1. Rewrite with TypeScript
2. Fixed the bug that duration() might return 0 when called many times with jitter parameters

$ npm install backo3

• min initial timeout in milliseconds [100]
• max max timeout [10000]
• jitter [0]
• factor [2]

var Backoff = require('backo3');
var backoff = new Backoff({ min: 100, max: 20000 });

setTimeout(function(){
  something.reconnect();
}, backoff.duration());

// later when something works
backoff.reset()
