In my opinion, there are two big things in Javascript's world-closure and prototype.
Question 1.What does prototype do in JavaScript?
In a single word, it's a feature that aimed at startup cing code duplication.We all know in computer world there is a famous philosophy-Don't repeat yourself.In classic object-oriented versions ages such as C ++/C #/Java, We have inheritance to encapsulate some common methods into a super class to reduce code lines.But in Javascript, there is no concept of class,
owns it.
Wm_vscroll = $0115;
When a standard vertical scroll bar of a window generates a rolling event, send this message to that window, and send it to the control wm_initmenu that owns it = $0116;
This message is sent when a menu is to be activated. It occurs in a user menu bar or presses a menu key, which allows the program to change the menu before display.

After the braces are defined, P still points to a valid entity. It indicates that he owns the object. The object is not destroyed because of its defined range.

Instead, you need to use the _ bridge_transfer keyword to release the variable that originally owns the object after type conversion. The text is a bit confusing. Let's take a l
