I have a question in a script where I am doing a Quiz, in my last Quiz my I put 3 answer options: A, B and C. Where if the answer is The sum 3 points for option X, 2 points for option Y and 1 point for Option Z. If the answer is B sum 2 points for option X, 3 points for option Y and 1 point for Option Z. If the answer is C adds 1 point for option X, 2 points for option Y and 3 points for Option Z.

Then the function checks which Option has more points and returns it.

But I want to modify it to the following function:

If the answer is A sum 4 points. If the answer is B sum 2 points. If the answer is C sum 0 points.

If the number of points is up to 10, return Option X. If the number of points is from 11 to 24, return option Y. If the number of points is greater than 24, return Option Z.

Here's part of the code:

self.jobs = [
    {
        title: 'Opção X',
        description: 'Descrição Opção X'
    },
    {
        title: 'Opção Y',
        description: 'Descrição Opção Y'
    },
    {
        title: 'Opção Z',
        description: 'Descrição Opção Z'
    }
    ];

self.job = 9999;

self.questions = [
    {
        text: 'Pergunta 1',
        answered: false,
        skipped: false,
        answers: [
            {
                text: 'A',
                selected: false,
                values: [3, 2, 1]
            },
            {
                text: 'B',
                selected: false,
                values: [2, 3, 1]
            },
            {
                text: 'C',
                selected: false,
                values: [1, 2, 3]
            }
        ]
    },

        skipped: false,
        answers: [

How to measure the performance and costs (processing and memory) of a frontend? Make div appear in hers after 2 seconds with jQuery

score 1 · Accepted Answer

To resolve the problem of the value of each letter, you should change the arrays [3, 2, 1] , [2, 3, 1] [1,2,3] [4, 2, 0] , [2, 4, 0], and [0, 2, 4] (respectively and in the 3 questions). The score you test on the "getResult" function, modifying the end of it:

getResult = function() {
    var results = [0, 0, 0];
    var soma = 0;

    angular.forEach(self.userAnswers, function(answer) {
        for(var i=0; i < self.jobs.length; i++) {
            results[i] += answer.values[i];
        }
    });

    for(var i=0; i < results.length; i++) {
        soma += results[i];
    }

    if (soma > 24)
        return 2; // Z
    else if (soma >= 11 && soma <= 24)
        return 1; // Y
    else
        return 0; // X
};

I imagine it to be this!
