Hi @BassamHajar - I liked how you used method chaining here to accomplish the desired results. I would like to add one thing here though. Although it might seem a small thing but giving appropriate names to variables inside methods like map, filter and reduce is quite important. I see that you have done a mix of both.

For example, the map method uses task as an internal variable correctly. However, filter method uses rate as the variable name when hour might have been more appropriate because we are filtering out hours here. Similarly, inside reduce, you have used acc and curVal which might have been coming from the APIs of the reduce method but having total, amount would have been more appropriate. Don't you think? 🙂

Please be mindful of variable naming conventions. Even though they are small things but they happen to make you lot better.


// eslint-disable-next-line no-unused-vars
const earnings = computeEarnings(maartjesTasks, maartjesHourlyRate);

// add code to convert `earnings` to a string rounded to two decimals (euro cents)

console.log(`Maartje has earned €${'replace this string with the earnings rounded to euro cents'}`);
// console.log(`Maartje has earned €${'replace this string with the earnings rounded to euro cents'}`);
console.log(`Maartje has earned € ${earnings}`);

Just FYI - you can also use arrow functions here to replace the function definition using function keyword with function expressions i.e

const doubleOddNumbers = numbers => numbers
  .filter(num => num % 2 !== 0)
  .map(num => num * 2);

}

const myNumbers = [1, 2, 3, 4];
