Try change the newOption initialization and text assignment:

JavaScript

function loaddropdown()
{
    var dropdown = document.getElementById("ddFAge");
    
    for(var i=1;i<=100;i++)
    {
        // var newOption = new Option[![enter image description here][1]][1];
        var newOption=document.createElement("option");
        newOption.innerHTML = i;  //innerHTML & not Text
        newOption.value = i;
        dropdown.options.add(newOption);
        
        //dropdown.options.add(newOption);

        //<option value="0"><--Select Age--></option>
    }
}

BTW, I am not sure where from you are using the value of i here. Above code would iterate 100 times and add the same thing to dropdown 100 times. I doubt if that is what you are trying here. Do check.
