var a = document.getElementsByTagName('input')[0];
var i = 0;
var plc = 'type A B C';
var speed = 300;

a.addEventListener('focus',triGr)

function triGr(){
if(i < plc.length){
a.placeholder += plc.charAt(i);
i++;
setTimeout(triGr, speed);
}
}

<input id="name" name="name" type="text"  placeholder="" required>
