      a = location.replace("https://exampl.example.repl.co");
      a.preventDefault();
      $.ajax({
        type:'POST',
        url:'/',
        //data:{
        //  todo:$("#todo").val()
        //},
        success:function(){
          var usetime = Date.now() - timeping;
          alert(usetime+"ms");
        }
      });

Hi @louis. Thank you for your post.

In order for the community to suggest ideas to help you solve your code issue it would be useful to share a link to your Repl.

Any error messages that you see appear when you attempt to run your code would also be useful to share here.

The first parameter of setInterval is a function, but you haven’t made a function. You also have a variable, a, which you don’t actually use.

Your code should look something like this:

setInterval(function() {
	// a isn't actually used here and so appears unnecessary
	a = location.replace("https://exampl.example.repl.co");
	a.preventDefault();
	// you could do
	// location.replace("https://exampl.example.repl.co").preventDefault();
	$.ajax({
		type: "POST",
		URL: "/",
		//data: {
			//todo:$("#todo").val()
		//},
		success: function() {
			// I'm assuming timeping is defined outside of this function, if not, this will produce an error
			alert((Date.now() - timeping) + "ms");
		}
	});
}, 1000);
