The parameters of the function refer to an object, and then perform operations on the object.

Function () means to call a function and execute this object.

If it is just the function itself without parentheses, it means the address of the function in memory.

The function itself is an object. When defining a function, the parameters can refer to any object.

If you want to execute a function, you must call it.

The scope of the function.
