If we need to consider fractional numbers, what should be added to the 'times' method?

If the times method currently only works with integers, to account for fractional numbers, the logic needs to be changed, as loops with fractional iterations don't make sense.

Instead, you can:

• Modify the method to accept a fractional number and call the passed function the necessary number of times, considering the fractional part, for example, by multiplying the result by the fractional part.
• Or create a method that returns an array with a fractional step.

An example in JavaScript, where times calls a function with indices, including fractional steps:

function times(n, callback) {
  const result = [];
  const step = 0.1; // for example, step 0.1
  for (let i = 0; i < n; i += step) {
    result.push(callback(i));
    if (i + step > n && n - i > 0) {
      result.push(callback(n)); // handle fractional part
    }
  }
  return result;
}

// Usage:
times(1, i => console.log(i.toFixed(1)));

If the method should simply repeat an action n times, where n is fractional, you can round or use logic with a probability of calling for the fractional part.
