如何使用remove方法从使用Vanilla JS的父项中删除列表项？

Question

警告：我的JavaScript代码看起来很乱。我仍然需要对其进行模块化

我正在尝试从父节点中删除列表项，这些列表项是由 addPhraseToDisplay 功能添加的。我用于此操作的代码在 buttonElement.innerHTML =“重新开始” 下已注释掉，因此请放大到该代码区域以节省时间 。

let missed=0;
const qwertyID=document.getElementById('qwerty');
const phraseID=document.getElementById('phrase');
const buttonElement=document.getElementsByClassName("btn__reset")[0];
const overLay=document.getElementById('overlay');
const phraseArray=["Hey man","This is weird","I am bored","That is nice","That is cool"];
const ul=document.getElementsByTagName('UL')[0];
const heading=document.querySelector('.title');


//picks random phrase from phraseArray,breaks phrase into character array
//returns arr---character array to be displayed
function getRandomPhraseAsArray(array) {
    index = Math.floor((Math.random() * array.length))
    let str=array[index];
    let arr=[...str];
    console.log(arr);
    return arr;
}

//appends each character as list items in ul
//takes arr in parameter
function addPhraseToDisplay(characterArray) {
    for (let i=0; i<characterArray.length; i+=1) {
        let char=characterArray[i];
        listItem=document.createElement('LI');
        listItem.textContent=char;
        if (char!==" ") { //make code cleaner
            listItem.classList.add("letter");
        }
        ul.appendChild(listItem);   
    }
}

//takes button as parameter and checks its letter
//checks letter class name in list, checks for match, and adds class show
function checkLetter(buttonKey) {
    buttonText=buttonKey.textContent;
    lettersList=document.getElementsByClassName('letter');
    let match=null;
    for (let i=0;i<lettersList.length;i+=1) {
        if (lettersList[i].textContent.toLowerCase()===buttonText) {
            lettersList[i].classList.add("show");
            match=true;
        } 
    }
    return match;
}

//compares number of letter classes with show classes and checks missed variable
function checkWin () {
    letterClassLength=document.getElementsByClassName('letter').length;
    showClassLength=document.getElementsByClassName('show').length;
    if (letterClassLength===showClassLength) {
        overLay.classList.add("win");
        heading.innerHTML="You win!";
        overLay.style.display="flex";
        buttons=document.querySelectorAll('.keyrow button'); //repeated code
        for (let i=0; i<buttons.length;i+=1) {
            buttons[i].disabled=false;
        }
    } else if (missed>=5) {
        overLay.classList.add("lose");
        heading.innerHTML="You lose!";
        overLay.style.display="flex";
        buttons=document.querySelectorAll('.keyrow button'); //repeated code
        for (let i=0; i<buttons.length;i+=1) {
            buttons[i].disabled=false;
        }
    }
    buttonElement.innerHTML="Start Over";
    buttonElement.addEventListener('click', ()=> {
        overLay.style.display="none";
        chosen=document.getElementsByClassName('chosen');
        show=document.getElementsByClassName('show');
        // list_items=document.querySelectorAll('letter');
        for (let i=0; i<chosen.length;i+=1) {
            chosen[i].classList.remove('chosen');
        }
        for (let i=0; i<show.length;i+=1) {
            show[i].classList.remove('show');
        }
        // for (let i=0; i<list_items.length;i+=1) {
        // ul.remove(list_items[i]);
        // }
        phraseDisplayed=getRandomPhraseAsArray(phraseArray);
        addPhraseToDisplay(phraseDisplayed);
    });
}

//listener event to button to hide overlay
buttonElement.addEventListener('click', ()=> {
    overLay.style.display="none";
});


//stores arr (character array) from function into variable 
//inputs variable (character array) into new function
let phraseDisplayed=getRandomPhraseAsArray(phraseArray);
addPhraseToDisplay(phraseDisplayed);


//adds class chosen to key and disables it
//if button pressed did not match, remove one try from scoreboard and update missed 
qwertyID.addEventListener('click', (e)=>{
    let button=e.target;
    button.classList.add("chosen");
    button.disabled="true";
    let letterFound=checkLetter(button);
    ol=document.getElementsByTagName('OL')[0];
    tries=document.getElementsByClassName('tries')[0];
    if (letterFound==null) {
        ol.removeChild(tries);
        missed+=1;
    }
    checkWin();
});

我尝试使用remove方法，但这没有用。而是在游戏重新启动时添加了必要的更多列表项。我没有正确使用它吗？我应该做些不同的事情吗？

我知道有一种重新启动程序的简便方法，但是应该按照该项目的说明手动重新启动相关变量，所以我不能使用快捷方式重新加载页面。
