I have written a short script that works pretty much as a quiz. It displays a dialogue box making a question and you input the answer. However, my intention is that whether the answers are provided in capital or lowercase text, the app should grant you a point regardless. My question is, how can I give a point regardless of text capitalization of the input? I saw someone using toUpperCase() at some point in the code, but I am not quite sure.
let questions = [
["Who created Demon Slayer?", 'Gotouge'],
['Who was the first demon that ever existed?', 'Muzan'],
['Who was the flame pillar of the Demon Slayer Corps?', 'Rengoku']
];
let item = '';
let score = 0;
function quiz (arr){
for (let i = 0; i<questions.length; i++){
let interrogate = prompt(`${arr[i][0]}`);
if(interrogate === arr[i][1]){
score++;
}
}
}
quiz(questions);
console.log(score);
This should be what you want, I simplify your code a little bit.
I also add trim() to remove white space in the end and begining.
let questions = [
["Who created Demon Slayer?", 'Gotouge'],
['Who was the first demon that ever existed?', 'Muzan'],
['Who was the flame pillar of the Demon Slayer Corps?', 'Rengoku']
];
let score = 0;
function quiz (arr){
for (let i = 0; i<questions.length; i++){
let interrogate = prompt(`${arr[i][0]}`);
if(interrogate.trim().toLowerCase() === arr[i][1].toLowerCase()) score++;
}
}
quiz(questions);
console.log(score);You can use both toLowerCase() and toUpperCase() before comparing the correct answer and the input from the user,
change this,
interrogate === arr[i][1]
as,
interrogate.toLowerCase() === arr[i][1].toLowerCase()
