 Function

3. Function Prototype
function func_name( arg0, arg1…)
{
//function body
return ret_val;
}

4. Lambda Property
var func_ptr = function( arg0, arg1, …)
{ Similar to function ptr in C
//function body
return ret_val;
}
var ptr = func_ptr ;
Treat function as variable!

5. Callback Function
var call_back = function welcome()
{
alert(“welcome here");
}
window.onload=call_back;
No parentheses
