You can place the debugger command in your code which will halt your program and require you to step through it. This only works if your Developer Console is open. If it is not, the browser will ignore the command.

function RunTest()
{
    let output = "";
    let demo1 = document.getElementById("demo1");
    for (let i = 0; i< 5; i++)
    {
        output +=`The number is ${i}<br />`;
        debugger;
    }
    demo1.innerHTML = output;
