Calling Javascript function on button click event in web forms asp.net

Question

I am trying to do simple speech recognition using p5 library.

Why the OnClientClick method is not recognizing/returning the resulted speech. Here is my form code

<form id="form1" runat="server">
    <asp:Button ID="iBtnTest" runat="server" OnClientClick="go()" Text="Listen" />
    <!-- <input type="button" onclick="go()" value="Listen" -->
</form>

and my javascript code is like this:

 let handle = new p5.SpeechRec();
 handle.onResult = () => { alert(handle.resultString) }       
 function go() { handle.start(); }

i have included all the libraries properly and the above code works if i toggle between the simple input which i have commented out.

What am i doing wrong? If this question has already been answered then please give me a link. Thank you..

You must add return methodName() within OnClientClick.

See this and change your JavaScript function as it is.
