when I run it gave me a NaN and I have tried many times. here's the javascript file and HTML file

javascrit file:

function MinButton(){
    var td1Text = document.getElementById("td1").textContent;

    // Get array of numbers from text
     var OriginalArray = td1Text.split(",").map(function(num){
       return parseInt(num,10);
     });
    
    // Get td2
    var Min =  document.getElementById("MinTable");
    
    // Set td2 to sorted array converted to string
    Min.textContent = parseInt(Math.min(OriginalArray));
}

HTML file:

<tr>
            

    <th>Original array</th>
                    <!--<td><input type="text" id="textO"  size="40"></td>-->
               

         <td id ="td1">1,5,7,-1,3</td>
        </tr>
    <tr>
                    <th>Sorted Array</th>
                    <td id="td2"></td>
    </tr>    
<input type="button" value="Find Min" id="Min" onclick="MinButton();">
