$w.onReady(function () {
let typing;
const text = "My text is here. Yes it's here."
let i = 0;
runTyping();
const showText = () => {
i++;
if(i > text.length){
i = 0;
clearInterval(typing);
return setTimeout(runTyping, 5000);
}
$w("#text1").text = text.slice(0, i);
}
function runTyping(){
typing = setInterval(() => showText(), 200);
}
});
