Tell us what’s happening:

I independently tested the tests on my local environment and they run perfectly, but I cannot pass the same tests on the website. I’m encountering issues with tests 4-6 and 11-14.

Your code so far

const config1 = {
  fault: false,
  phases: [
    { color: "green", duration: 5 },
    { color: "yellow", duration: 2 },
    { color: "red", duration: 4 }
  ]
};

const config2 = {
  fault: false,
  phases: [
    { color: "red", duration: 3 },
    { color: "yellow", duration: -2 },
    { color: "green", duration: 6 }
  ]
};

const config3 = {
  fault: true,
  phases: [
    { color: "green", duration: 5 },
    { color: "yellow", duration: 2 },
    { color: "red", duration: 6 }
  ]
};

const config4 = {
  fault: false,
  phases: []
};

function runSequence (config, cycles){
  if (config.phases.length === 0){
    console.log("No phases found");
    return;
  }

  if (config.fault) {
    console.log("Faulted phase!");
    return;
  }

  for (let i = 0; i < cycles; i++){
    for (elem of config.phases){
        if (elem.duration <= 0) {
            console.log("Invalid phase detected");
        } else {
            console.log(`Switching to ${elem.color} for ${elem.duration} s`);
      }
    }
  }
}

function generateTimeline (config, cycles){
  const counts = [];
  let count = 0;
  for (let i = 0; i < cycles; i++){
    for (elem of config.phases){
      count += elem.duration;
      counts.push(count);
    }
  }
  return counts;
}

Welcome to the forum @Rosenwald,

If I test like this: console.log(runSequence(config1, 1)), I see an error in the console:

ReferenceError: elem is not defined

Happy coding
