Constructors never have an explicit return type. Constructors cannot be directly invoked (the keyword “new” invokes them). Constructors should not have non-access modifiers. Java constructors perform the following tasks in the following order: Call the default constructor of the superclass if no constructor is defined.
The binary logical operators returned a Boolean value in early versions of JavaScript, but now they return one of the operands instead. The left–operand is returned, if it can be evaluated as : false, in the case of conjunction: (a && b), or true, in the case of disjunction: (a || b); otherwise the right–operand is returned. Automatic type ...
The Function constructor can be used to trigger execution of JavaScript code contained in a string as if it were native JavaScript. So, for example, the statement alert() is equivalent to Function("alert()")(). The Function constructor can be retrieved in JSFuck by accessing the constructor property of a well known function, such as []["filter ...
An early example using a Javadoc-like syntax to document JavaScript was released in 1999 with the Netscape/Mozilla project Rhino, a JavaScript run-time system written in Java. It included a toy "JSDoc" HTML generator, versioned up to 1.3, as an example of its JavaScript capabilities. [2]
In class-based programming, a factory is an abstraction of a constructor of a class, while in prototype-based programming a factory is an abstraction of a prototype object. A constructor is concrete in that it creates objects as instances of one class, and by a specified process (class instantiation), while a factory can create objects by instantiating various classes, or by using other ...
The factory method design pattern solves problems such as: How can an object's subclasses redefine its subsequent and distinct implementation? The pattern involves creation of a factory method within the superclass that defers the object's creation to a subclass's factory method.

The builder pattern is a design pattern that provides a flexible solution to various object creation problems in object-oriented programming.The builder pattern separates the construction of a complex object from its representation.
