Breaking an array in JavaScript

I'm developing a pure JavaScript hangman game and facing an issue with splitting words from an array into single letters. When I split the array, I get "," for every letter.

For example, when I split the word [station], it returns "s,t,a,t,i,o,n".

My goal is to split the word without adding the "," between letters.

Below is the code snippet I'm currently using:

// Array of words for the hangman game
let words = ["definition", "programming", "relation", "station", "gamification", "playstation"];

// Randomly select a word from the array
let random = Math.floor(Math.random(words) * words.length);

// Split the selected word into individual letters (e.g., station to [s,t,a,t,i,o,n])
let wordSplit = words[random].split('');

// Display the word split into letters
let wordLetters = document.getElementById("letters")
wordLetters.innerHTML = wordSplit;

function wordInput(){
    let lettersDiv = document.getElementById("letters");
    let html = "<p id = 'letters'>" + wordSplit + "</p>";
    return html;
}

See how it displays

Answer №1

One alternative is to substitute

let wordSplit = words[random].split('');

for

let wordSplit = words[random].split('').join(" ");  // adding a space in the join method 

Answer №2

const splitWord = words[random].split('');

After executing this line of code, splitWord will be set to

["d", "e", "f", "i", "n", "i", "t", "i", "o", "n"]
, forming an array without any commas.

However, a complication arises when you use the following code:

wordLetters.innerHTML = splitWord;

It is essential to note that the HTML DOM is only capable of understanding strings as a datatype (no integers, arrays, etc.). Hence, when you attempt the command mentioned above, the DOM Renderer is unable to assign the innerHTML as an array variable. Consequently, the toString() method is invoked instead.

Effectively, the aforementioned command is interpreted internally as:

wordLetters.innerHTML = splitWord.toString()

Calling toString() on arrays results in a comma-separated string, which explains the appearance of commas in the output.

The issue does not stem from the splitting process but from the webpage's structure. To address this, you will need to employ a .map function to allocate each character to a separate div element, or a similar approach.

Alternatively, you can utilize:

wordLetters.innerHTML = splitWord.join(' ')

This alternative will substitute the commas with spaces.

Answer №3

It seems like there might be some confusion with the issue, but using the .join("") method should solve the problem:

let string = "<p id = 'letters'>" + wordArray.join("") + "</p>";

Answer №4

I am uncertain of the accuracy, but I believe that utilizing the .join("") method may resolve the issue.

let separatedWords = words[random].split('').join(" ")

Answer №5

Utilize spacing within the split function.

For instance:

const splitWords = words[random].split(' ').join('');
