Trivia guessing game (removing space bar in string array)

I'm a javascript noob I began a Bootcamp to improve my knowledge. I was tasked with creating a hangman style guessing game. I pretty much pulled a template repo from GitHub and themed it after Bob Ross. The problem I'm having is the array of words to guess all contain a space.

(CADMIUM YELLOW, PHTHALO GREEN, PHTHALO BLUE, VAN DYKE BROWN, PRUSSIAN BLUE, TITANUM WHITE, YELLOW OCHRE, ALIZIRIN CRIMSON)

This space is considered a value and is assigned an _ just like the letters. If anyone could help me solve I would be very grateful.

// color list
var words = ["CADMIUM YELLOW", "PHTHALO GREEN", "PHTHALO BLUE", "VAN DYKE BROWN", "PRUSSIAN BLUE", "TITANUM WHITE", "YELLOW OCHRE", "ALIZIRIN CRIMSON"];

var maxNumGuesses = 8; 
var guessedLetters = []; 
var ansWordArr = []; 
var numGuessesRemaining = 0; 
var numWins = 0; 
var numLosses = 0; 
var isFinished = false; 
var ansWord; // word being played


function setup() {
    //random word from words list
    ansWord = words[Math.floor(Math.random() * words.length)];

    ansWordArr = [];


    for (var i = 0; i < ansWord.length; i++) {
        ansWordArr[i] = "_";
    }


    numGuessesRemaining = maxNumGuesses;
    guessedLetters = [];


    document.getElementById("giphy-embed").src = "";

    document.getElementById("numGuesses").style.color = "";

    updateScreen();
};

//updates the HTML from the functions
function updateScreen() {
    document.getElementById("numWins").innerText = numWins;
    document.getElementById("numLosses").innerText = numLosses;
    document.getElementById("numGuesses").innerText = numGuessesRemaining;
    document.getElementById("answerWord").innerText = ansWordArr.join("");
    document.getElementById("guessedLetters").innerText = guessedLetters;

};

//function to check the key that's pressed
function checkGuess(letter) {
    //if letter is not in guessedLetters array then push the letter to the array
    if (guessedLetters.indexOf(letter) === -1) {
        guessedLetters.push(letter);
        //if the letter isn't in the answer word then -1 the numGuessesRemaining
        if (ansWord.indexOf(letter) === -1) {
            numGuessesRemaining--;
            //if numGuessesRemaining is 3 or less then change the color
            if (numGuessesRemaining <=3) {
                document.getElementById("numGuesses").style.color = "#e12d2e";
            }
            //if letter is in answer then replace the positioned "_" with the letter
        } else { 
            for (var i = 0; i < ansWord.length; i++) {
                if (letter === ansWord[i]) {
                    ansWordArr[i] = letter;
                } 
            }                
        }
    }
