Check if the intended javascript function exist or not.

Often it is a best practice to call function only if exists..

So this can be achieved calling our required function in:
function fExist(f){
if(typeof f == "function"){
return f();

function foo(){
console.log("I am a function");


Result wil be:

because we have defined function "foo"...
