javascript unnamed function parameter code example

Example: anonymous function javascript

// There are several definitions

// Non-anonymous, you name it
function hello() { /* code */ }
// Call as usual
hello()

// The myriad of anonymous functions

// This is actually anonymous
// It is simply stored in a variable
var hello = function() { /* code */ }
// It is called the same way
hello()

// You will usually find them as callbacks
setTimeout(function(){ /* code */ }, 1000)
// jQuery
$('.some-element').each(function(index){ /* code */ })

// Or a self firing-closue
(function(){ /* code */ })()
