how to append an array inside a ul in javascript?

问题

I am having trouble appending an array called phrases to a method called addPhraseToDisplay(). Here is the array:

class Game {
constructor() {
    this.missed = 0; // this property will be used as a counter for the total of 5 tries
    this.phrases = ["life is strange","success does not come easy", "seven swans swimming", "guess the word", "wild goose chase"] 
}

what I want to do is append the array into as list items, I tried to target the phrases like this newListItem.textContent = (this.phrases);, but that didn't work

addPhraseToDisplay() {
   //Create a reference to ul element
    const myList = document.getElementById('myList');

    //Crete new list items
    let newListItem = document.createElement('li');
    newListItem.textContent = (this.phrases);

this is html code where I would like the array to be inside as list items

<!--My phrases need to be appended down here, div is parent element -->
        <div id="phrase" class="section">
            <ul id="myList">

            </ul>

if someone could help I would appreciated

Hello you can try this:

<html>
<body>

<div id="myList">

</div>

<p>Click the button to append an item to the end of the list.</p>

<button onclick="myFunction()">Try it</button>

<script>
function myFunction() {
    //Creating element with html tag .... and append it to another element
    var node = document.createElement("UL");
    var textnode = document.createTextNode("Water");
    node.appendChild(textnode);
    document.getElementById("myList").appendChild(node);
}
</script>


</body>
