What is a function literal in JavaScript?

A function literal is an expression that defines an unnamed function. You can try to run the following code to implement function literal in JavaScript.

Example

<html>
   <head>
      <script>
         <!--
            var func = function(x,y){ return x*y };

            function secondFunction() {
               var result;
               result = func(10,20);
               document.write ( result );
            }
         //-->
      </script>
   </head>
   <body>
      <p>Click the following button to call the function</p>

      <form>
         <input type = "button" onclick = "secondFunction()" value = "Call Function">
      </form>
   </body>
</html>
