What is the meaning of : ReferenceError: Strict mode forbids implicit creation of global property 'myLyst' ?

I'm trying to store the ul element inside myList.

index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>DOM Manipulation</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <ul>
            <li id="first">First Item</li>
            <li id="second">Second Item</li>
            <li id="third">Third Item</li>
        </ul>
        <script src="app.js"></script>
    </body>
</html>
app.js 
let myList;
let firstListItem;
myLyst = document.getElementsByTagName('ul')[0];

You have a typo.

myLyst != myList
