Node.js

Technical Specification

Create a script that logs a heartbeat message every minute, and stops after 5 runs.

Input/Output Samples

Input:run script

Output:Heartbeat #1 ... Heartbeat #5 then exit

Optimal Logic Path

let count = 0;
const maxRuns = 5;

const id = setInterval(() => {
  count++;
  console.log("Heartbeat #", count);
  if (count >= maxRuns) {
    clearInterval(id);
  }
}, 60000);
