How to make arrays go from one to one?

Question

I’m trying to get the website title here, always change its title from time to time but I don’t know how to do it. ignore the Alert it’s just for me to see how it looks

var titulo = [algum, valor, em, algum, lugar]

for (i = 0; i < 2; i++) {
    arraytitu[i] = setInterval(function () {
        if (i < 3) {
            alert(arraytitu);
            i++;
        } else {
            clearInterval(tmp[i])
        }
    }, 1000);
}```

You don’t need a bow for. With only setInterval you already can. Just go through each index of the array to the end. When the variable value indice is equal to the size of the array, cancel the timer:

var titulo = ['tit1', 'tit2', 'tit3', 'tit4', 'tit5'];
var indice = 0;
var intervalo = setInterval(function () {
   if (indice < titulo.length) {
      console.log(titulo[indice]);
   } else {
      clearInterval(intervalo);
      console.log("Acabou!");
   }
   indice++;
}, 1000);

Edit

If you want an infinite loop in the array, you can do it this way:

var titulo = ['tit1', 'tit2', 'tit3', 'tit4', 'tit5'];
var indice = 0;
var intervalo = setInterval(function () {
   console.log(titulo[indice]);
   indice++;
   if (indice == titulo.length) indice = 0;
}, 1000);
