How to define a JavaScript function using Function() Constructor?

The Function() constructor expects any number of string arguments. The last argument is the body of the function - it can contain arbitrary JavaScript statements, separated from each other by semicolons.


You can try to run the following code to invoke a function with new Function Constructor −

         var func = new Function("x", "y", "return x*y;");

         function multiplyFunction(){
            var result;
            result = func(15,35);
            document.write ( result );
      <p>Click the following button to call the function</p>

         <input type = "button" onclick = "multiplyFunction()" value = "Call Function">
