Function to calculate and return numbers within an array

  • 772

I don't understand the exercise very well, I know that I have to put an accumulator so that each point counts, but I don't know how to add the points later. Thanks for your help.

  function puntosDelEquipo(array) {
      // la funcion recibe un array con los resultados de los partidos del campeonato de futbol de un equipo
      // en este formato ["3:1", "2:2", "0:1", ...]
      //la funcion debe calcular y retornar cuantos puntos consiguio el equipo teniendo en cuenta:
      //que su resultado es el primero en cada string
      // un partido ganado suma 3 puntos, empate suma 1 punto, y perder 0!
      // Tu código aca:
    array.tostring().split(":").lenngth;
      var valor = 0;
      if(valor > 1 == 3)
  }
javascript

    This is my solution that I explain below:

    • I assign a counter variable to add the points (3,1,0)
    • I do an iteration over the array to apply the method splitwhose separator will be : (the colon) to each element.
    • Then it only remains to validate the result of your team (team_a) vs the opposing team (team_b) using the ternary operator

    function puntosDelEquipo(array){
    let counter = 0;
    array.forEach(result => {
      const resultSplit = result.split(":");
      const team_a = parseInt(resultSplit[0])
      const team_b = parseInt(resultSplit[1])
      const points = team_a > team_b ? 3 : team_a == team_b ? 1 : 0
      counter += points
    })
    return counter
}

puntosDelEquipo(["3:1", "2:2", "0:1", "6:5"])

    I hope this solution can help you
