In Mozilla's JavaScript, since version 1.7, destructuring assignment allows the assignment of parts of data structures to several variables at once. The left hand side of an assignment is a pattern that resembles an arbitrarily nested object/array literal containing l-lvalues at its leaves that are to receive the substructures of the assigned ...
If the right-hand side of the assignment is a single variable (e.g. an array or structure), the feature is called unpacking [17] or destructuring assignment: [18] var list := {0, 1} a, b := list The list will be unpacked so that 0 is assigned to a and 1 to b .
destructuring assignment, and; algebraic data types. The intent of these features was partly to better support programming in the large, and to allow sacrificing some of the script's ability to be dynamic to improve performance.

Most typed functional programming languages implement tuples directly as product types, [1] tightly associated with algebraic data types, pattern matching, and destructuring assignment. [2] Many programming languages offer an alternative to tuples, known as record types , featuring unordered elements accessed by label. [ 3 ]
MDN Web Docs, previously Mozilla Developer Network and formerly Mozilla Developer Center, is a documentation repository and learning resource for web developers. It was started by Mozilla in 2005 [ 2 ] as a unified place for documentation about open web standards, Mozilla's own projects, and developer guides.
In object-oriented programming, a destructor (sometimes abbreviated dtor [1]) is a method which is invoked mechanically just before the memory of the object is released. [2] It can happen when its lifetime is bound to scope and the execution leaves the scope, when it is embedded in another object whose lifetime ends, or when it was allocated dynamically and is released explicitly.
Microsoft Developer Network (MSDN) was the division of Microsoft responsible for managing the firm's relationship with developers and testers, such as hardware developers interested in the operating system (OS), and software developers developing on the various OS platforms or using the API or scripting languages of Microsoft's applications.
