Answer 1

You can use setInterval to show elements one by one after 3 seconds delay:

s=["John", "Alex", "Mark"];

var i = 0;
var id = setInterval(function(){                
            if(i > s.length) {                  
                clearInterval(id);                  
            }
            else{
                console.log(s[i++]);
            }
}, 3000);
