Question

I want to define a self executing anonymous function, but have it run several times with different parameters.

(function(x){ console.log(x*x)})(2)
// output: 4

// I know this syntax is wrong, I am
// demonstrating how I would imagine it being implemented
(function(x){ console.log(x*x)})(2)(5)
// output is error, desired output: 4{Newline}25

Is it possible?

Edit: Based on answer from @Charmander, it seems it is possible
and almost certainly a bad idea, but this works as I would expect…

(function(x){ console.log(x*x); return arguments.callee})(2)(5)

Answer 1

You can either store the anonymous function in a variable.

var someFunction = function(x){
   console.log(x*x);
};

someFunction(5);
someFunction(6);

Or you could have the function return itself if you are really bent on making it an immediately-invoked function expression (iife).

(function(x){
   console.log(x*x);
   return arguments.callee;
})(5)(6);
