Question 329759 in Javascript Question posted in
A very good W3school tutorial can be found here.

Javascript – How can I get the name of an array inside of another array?

I am currently making a word-guessing minigame. In this, I have one Array called PlayingArrays and a bunch of other arrays that contain names. I am using Math.random() to get the indices.

Question: How can I get the name of the array?

Note: The alert on line 19 in inside of playGame() is alert(`${category}`). When this runs, I get every word inside of the array.

const difficultyArticle = document.querySelector('#difficulty-article');
const difficultyOptions = document.querySelector('#difficulty-options');
const startGameButton = document.querySelector('#start-game');
const playArticle = document.querySelector('#play-article');
const resultArticle = document.querySelector('#result-article');

let maxTime = 0;
let currentTime = 0;
let currentSeconds = 0;
let currentMinutes = 0;
let lives = 0;
let difficulty;

function playGame() {
    let wordInfo = determineWord();
    let randomWord = wordInfo.word;
    let category = wordInfo.category;

    alert(`${randomWord}, ${category}`);
}

function determineWord() {
    let categoryIndex = Math.round(Math.random() * (PlayingArrays.length - 1));
    let category = PlayingArrays[categoryIndex];
    let wordIndex = Math.round(Math.random() * (category.length - 1));
    let randomWord = category[wordIndex];

    return {
        word: randomWord,
        category: category
    }
}

playArticle.classList.add("hidden");
resultArticle.classList.add("hidden");

startGameButton.addEventListener('click', (event) => {
    playGame();
})

    How can I get the name of the array?

    You can’t. When you add arrays like Animals, People, etc into PlayingArrays, all you’ve got is a 2-dimensional array. The variable names are not kept. I’d suggest using an object instead

    const PlayingArrays = {
  Animals,
  People,
  Buildings,
  Climates,
  Countries,
  States,
  Capitals,
  Foods,
};

    Then you can use the object keys to get your category

    const categories = Object.keys(PlayingArrays);
const category = categories[(Math.floor(Math.random() * categories.length)];
const words = PlayingArrays[category];
const randomWord = words[Math.floor(Math.random() * words.length)];

    Getting the name of the variable doesn’t make that much sense, I think a better way might be to have another array of the names and use the same indexes:

    const PlayingArrayNames = [
    'Animals', 
    'People',
    'Buildings',
    'Climates',
    'Countries',
    'States',
    'Capitals',
    'Foods'
]

    Then you can just use the same index to get the names.

    Or you could modify your PlayingArrays array to be an array of objects, with a name field. It does mean you would have to reference the array inside the object before you use it.

    const PlayingArray = [
    {name: 'Animals', values: Animals}, 
    {name: 'People', values: People},
    {name: 'Buildings', values: Buildings},
    {name: 'Climates', values: Climates},
    {name: 'Countries', values: Countries},
    {name: 'States', values: States},
    {name: 'Capitals', values: Capitals},
    {name: 'Foods', values: Foods}
]
