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

// This is actually anonymous
// It is simply stored in a variable

// It is called the same way
hello()
// You will usually find them as callbacks
setTimeout(function(){ /* code */ }, 1000)
// jQuery

// Or a self firing-closue
(function(){ /* code */ })()//Anonymous function; It's not assigned to an indentifier
Array.forEach((arguments) => {
//This is an anonymous function
})
function forEach(arguments) {
//This is NOT an anonymous function
}
