New

Struct New 

Source
pub struct New { /* private fields */ }
Expand description

The new operator lets developers create an instance of a user-defined object type or of one of the built-in object types that has a constructor function.

The new keyword does the following things:

  • Creates a blank, plain JavaScript object;
  • Links (sets the constructor of) this object to another object;
  • Passes the newly created object from Step 1 as the this context;
  • Returns this if the function doesn’t return its own object.
