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.
