function typeOfArgument() {
    let argument = document.getElementById("argument").value;
    let typeOfArgument = "string";
    
    try{
        if (argument === "undefined") {
            typeOfArgument = "undefined"
        }
        else if(argument === "null" || JSON.parse(argument).constructor === Object || JSON.parse(argument).constructor === Array)
        {
            typeOfArgument = "object";
        }
        else if (!isNaN(parseInt(argument))) {
            typeOfArgument = "number";
        }
        else if(argument === "true" || argument === "false") 
        {
            typeOfArgument = "boolean"
        }
        document.getElementById("mypara").innerHTML = "type of " + argument + " is " + typeOfArgument;
    }
    catch(e)
    {
        console.log("exception")
        document.getElementById("mypara").innerHTML = "type of " + argument + " is " + typeOfArgument;
    }
}

<p>Enter argument</p>
<label>Argument</label>
<input type="text" id="argument"/>
<br/>

<button onclick="typeOfArgument();">Submit</button>
<p id="mypara">The output will be displayed here</p>
