Firefox выдает ошибку размера распределения в строке шаблона

---

hey guys i dont seem to know whats the problem here,

never encountered before, i get allocation size error in the 
console, and the IDE telling me the string too long too,

second question is how do i apply this shuffle function into the code?

       var gNums = []
    var gInterval = null
    var gBoard = creatBoard()
    
    
    renderBoard()
    function renderBoard() {
        strHtml = ''
        for (var i = 0; i < gBoard.length; i++) {
            var row = gBoard[i]
            strHtml += '<tr>'
            for (var j = 0; j < row.length; i++) {
                cellvalue = row[j].value
                var className = (row[j].isClicked) ? 'clicked' : ''
                strHtml += `
                <td class="${className}" onclick="numClicked(this)">
                ${cellvalue}
                </td> `
    
            }
            strHtml += `</tr>`
        }
        var ElBoard = document.querySelector('.board')
        ElBoard.innerHTML = str.strHtml
    
    }
    
    
    
    function creatBoard(difficulty = 16) {
        resetNums()
        var board = []
        for (var i = 0; i < Math.sqrt(difficulty); i++) {
            board[i] = []
            for (var j = 0; j < Math.sqrt(difficulty); j++) {
                board[i][j] = creatCell()
            }
    
        } return board
    
    }
    
    
    
    function creatCell() {
        var num = gNums.splice(gNums.length - 1, 1)
        return {
            value: Number(num),
            isClicked: false
        }
    }
    
    
    
    
    
    resetNums()
    function resetNums(difficulty = 16) {
        gNums = []
        for (var i = 0; i <= difficulty; i++) {
            gNums.push(i)
        }
        return gNums
    }
    
    
    
    
    function shuffle(array) {
        var m = array.length, t, i;
        while (m) {
            i = Math.floor(Math.random() * m--);
            t = array[m];
            array[m] = array[i];
            array[i] = t;
        }
    
        return array;
    }

Что я уже пробовал:

я попробовал разбить строку пробелами для большей читабельности и найти ошибку, которая выглядит нормально.
