For example, the pyramid of doom is commonly seen when checking for null pointers or handling callbacks. [1] Two examples of the term are related to a particular programming style in early versions of JavaScript , [ 2 ] and the nesting of if statements that occurs in object-oriented programming languages when one of the objects may be a null ...
The object pool pattern is a software creational design pattern that uses a set of initialized objects kept ready to use – a "pool" – rather than allocating and destroying them on demand. A client of the pool will request an object from the pool and perform operations on the returned object.

Peephole optimization is an optimization technique performed on a small set of compiler-generated instructions, known as a peephole or window, [1] [2] that involves replacing the instructions with a logically equivalent set that has better performance.
The indirection pattern supports low coupling and reuses potential between two elements by assigning the responsibility of mediation between them to an intermediate object. An example of this is the introduction of a controller component for mediation between data (model) and its representation (view) in the model-view-controller pattern.
When using a language that supports multiple paradigms, the developer chooses which paradigm elements to use. But, this choice may not involve considering paradigms per se. The developer often uses the features of a language as the language provides them and to the extent that the developer knows them.
JoCaml is the first language where the join-pattern was implemented. Indeed, at the beginning all the different implementation was compiled with the JoCaml Compiler. JoCaml language is an extension of the OCaml language. It extends OCaml with support for concurrency and synchronization, the distributed execution of programs, and the dynamic ...
He has started up several of the conferences in the Pattern Languages of Programs (PLoP) conference series and is a longstanding pattern author and PLoP shepherd. His pattern form, the "Coplien Form," [ 2 ] is a simplified way to structure a pattern in preparation for writing a more literate version in Alexandrian form.
