How can I find what quarter of the year a month is in based on the number the month corresponds to-CodePudding

I am on codewars, here is the challenge:

Given a month as an integer from 1 to 12, return to which quarter of the year it belongs as an integer number.
For example: month 2 (February), is part of the first quarter; month 6 (June), is part of the second quarter; and month 11 (November), is part of the fourth quarter.

Here is what I tried:

const quarterOf = (month) => {
  // Your code here
  if (month <= 3) {
    return 1
  } else if (6 >= month > 3) {
    return 2
  } else if (9 >= month > 6) {
    return 3
  } else if (12 >= month > 9) {
    return 4
  }
}

This doesn't seem to work, I know I could assign each month a variable, but I'm trying to improve my skills, can someone explain why this does not work to me?

This is simple you are trying to check for two conditions in one statement try to use && and || for separation of conditions your code will look like this:

const quarterOf = (month) => {
  // Your code here
  if (month <= 3) {
  return 1
  } else if (6 >= month && month > 3) {
    return 2
  } else if (9 >= month && month > 6) {
    return 3
  } else if (12 >= month && month > 9) {
    return 4
  }
}

All you need is

const quarterOf = (month) =>
  {
  if (month <=  3) return 1
  if (month <=  6) return 2
  if (month <=  9) return 3
  return 4
  }

const quarterOf = month => Math.ceil(month / 3);

Probably the simples solution unless you want 3x if:

const quarterOf = (month) {
  return Math.floor(month / 3   1);
}
