In computer programming, the async/await pattern is a syntactic feature of many ... Hack, Julia, Dart, Kotlin, Rust, [2] Nim, [3 ... Python added support for async ...
Unlike Smalltalk, in Dart the value of a cascaded method invocation is the receiver (base object), not the value of the (uncascaded) method invocation, and thus there is no need for yourself. Dart uses properties , and thus rather than using method syntax for getters and setters ( foo.getBar(); foo.setBar(b); ), it uses field value/assignment ...
In computer science, futures, promises, delays, and deferreds are constructs used for synchronizing program execution in some concurrent programming languages.Each is an object that acts as a proxy for a result that is initially unknown, usually because the computation of its value is not yet complete.
Mixin programming is a style of software development, in which units of functionality are created in a class and then mixed in with other classes. [6] A mixin class acts as the parent class, containing the desired functionality. A subclass can then inherit or simply reuse this functionality, but not as a means of specialization.
In Python, returning self in the instance method is one way to implement the fluent pattern. It is however discouraged by the language’s creator, Guido van Rossum, [3] and therefore considered unpythonic (not idiomatic) for operations that do not return new values. Van Rossum provides string processing operations as example where he sees the ...
Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should favor polymorphic behavior and code reuse by their composition (by containing instances of other classes that implement the desired functionality) over inheritance from a base or parent class.

The Dart software development kit (SDK) ships with a standalone Dart runtime. This allows Dart code to run in a command-line interface environment. The SDK includes tools to compile and package Dart apps. [30] Dart ships with a complete standard library allowing users to write fully working system apps like custom web servers. [31]
Method chaining is a common syntax for invoking multiple method calls in object-oriented programming languages. Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results.
