Sure, they are pretty and make a really strong statement about the meat, but many high-dollar restaurants reportedly draw their grill marks on with a meat-marker, while others brush on a coat of sugar water prior to it hitting the hit grill.
How to call Function ? You call a Function procedure by using the procedure name, followed by the argument list in parentheses, in an expression. You can omit the parentheses only if you are not supplying any arguments. However, your code is more readable if you always include the parentheses.
Callback function is hard to trace, but sometimes it is very useful. Especially when you are designing libraries. Callback function is like asking your user to gives you a function name, and you will call that function under certain condition. For example, you write a callback timer. It allows you to specified the duration and what function to call, and the function will be callback accordingly. âRun myfunction() every 10 seconds for 5 timesâ. Or you can create a function directory, passing a list of function name and ask the library to callback accordingly.
