Why setInterval instead of timeout?

[pateketrueke]

I like your project and reading between lines I found this:

ckt-breaker/index.js

Line 40 in d3cd3cb

setInterval(() => {

I did not executed your code yet, but I can see those intervals will never cleared.

Is this right or i'm losing something?

As you can see i maintain an error rate for the service, I have to reset current error count in each interval.
