f = function() or function f ()

[scudsucker]

Hi- I've been away from flash for a while, and have just written a quick game, to test my skills...

One thing i have forgotten/missed:

What is the difference between these two:

code:

---

function f() {

// do somthing

}

---

code:

---

f=function() {

// do something

}

---

AFAIK, there is almost no difference between them. The only difference that I notice about them is this:
You can only declare functions from other reference (timeline or object/array) using the latter form:

code:

---

_global.myFn = function()

{

// codes

}

---

or

code:

---

myObject.myFn = function()

{

// codes

}

---

and not

code:

---

function myObject.myFn ()

{

// codes

}

---

Furthermore, the functions declared in the second form can be declared using var:

code:

---

var myFn = function()

{

// codes

}

---

Therefore, the second form is advantageous.

Yes, I wrote out about 200 lines of code in two sessions and noticed that I had used the two different syntaxes, yet everything was working.

I usually use the second, I recall.

Thanks!

another difference, functions defined using

function functionName() {

}

can be called before the function declaration in your code, for example,

code:

---

sayHello();



function sayHello() {

    trace("hello");

}

---

works, but

code:

---

sayHello();



sayHello = function() {

    trace("hello");

};

---

doesn't.
