Typing animation for total beginner.. help!

There’re many posts about it in the forum. You can search for it.
Basically you need something like:

const intervalInMilliseconds = 300;// interval between letters
const text = 'Some text some text';//the full text
let typingInterval;
$w.onReady(() => {
$w('#text1').text = '';
typingInterval = setInterval(typeItUp, intervalInMilliseconds);
})

function typeItUp(){
if($w('#text1').length >= text.length){
return clearInterval(typingInterval);//to stop when the entire text is displayed
}
$w('#text1').text = text.substring(0, $w('#text1').text.length + 1);//here you add one character every time.
})
