Javascript - Given an array cedulas = [200, 100, 50, 20, 10, 2]

Question

Good Afternoon!

Given the function

function caixaEletronico(amount){

  let totalAvailable = 1000
  let cedulas = [200,100,50,20,10,5,2]

  if (isNaN(amount) || typeof(amount) === 'string' || amount < 1 || amount > totalAvailable || amount === 3 || amount === 1) {
    return console.log(
      " Valor incorreto!! Cédulas disponíveis neste terminal: R$2,00 R$5,00 R$10,00 R$20,00 R$50,00 R$100,00 R$200,00 | Limite saque R$1.000,00"
    );
  }

  const newArrCedulas = cedulas.map(function(cedula) {
      cedulas = Math.floor(amount / cedula)
      amount -= cedulas * cedula
        return cedulas
  })

  console.log(
    `Notas entregues:
    ${newArrCedulas[0]} nota(s) de R$200,00, ${newArrCedulas[1]} nota(s) de R$100,00, ${newArrCedulas[2]} nota(s) de R$50,00 e ${newArrCedulas[3]} nota(s) de R$20,00, ${newArrCedulas[4]} nota(s) de R$10,00, ${newArrCedulas[5]} nota(s) de R$5,00, ${newArrCedulas[6]} nota(s) de R$2,00`
  )

}
caixaEletronico(88)

I’m having trouble specifically returning in some even numbers this is one of them, where the number 8 should return 4 2 ballots.

In case anyone can help me with the validation.

const newArrCedulas = cedulas.map(function(cedula) {
    cedulas = Math.floor(amount / cedula)
    if ((amount == 6 || amount == 8) && cedula == 5) {
      return 0;
    }
    amount -= cedulas * cedula
    return cedulas
})
