RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including t-minus. Try it out:
var Timer = require("t-minus")
var countdown = new Timer("03"
, function(){ console.log("time is up!")}
, function(){
if(this.secs % 10 === 0 && this.getTotal() < 60 && this.secs)
console.warn("ONLY " + this.secs + " SECONDS REMAINING");
else console.log(this.getTimerUI());
});
