Please help !, i dont know why the correct answers are not counting

var quiz = [ {question : "what is your name?", answer : "uche" },

{question : "how old are you ?", answer : "twenty"}, {question : "what is your profession", answer:"developer"}

]; var correctanswers = 0; var wronganswers= 0; var html; var response; var questionss; var answerss;

On this line, the count is not increased, but set to (positive) 1::

    correctanswers = +1;

What you probably intended here was to use the addition assignment operator instead ("correctanswers += 1")
