如何创建一个柜台

I would like to create a counter in which I can set a starting number and that every second increases by one. I need the counter to be integrated into a page of my website. I have no idea how to create it. Thank you everyone

This is a javascript question.

var i=0;
setInterval(function(){
    i++;
    //add_code to update html text to i
,1000);
