Flapjax
Encyclopedia
Flapjax is a programming language built atop JavaScript
. It provides a spreadsheet
-like dataflow computation
style, making it easy to create reactive
Web pages without the burden of callbacks
and potentially inconsistent mutation. Flapjax can be thought of in two ways: either as a library, for use in regular JavaScript programs, or as a new language that the compiler converts into generic JavaScript. In either case, the resulting programs can be run in a regular Web browser. In addition, Flapjax comes with persistent storage and a simple API that masks the complexity of using AJAX
, along with sharing and access-control
for server data.
The Flapjax compiler is written in Haskell
.
JavaScript
JavaScript is a prototype-based scripting language that is dynamic, weakly typed and has first-class functions. It is a multi-paradigm language, supporting object-oriented, imperative, and functional programming styles....
. It provides a spreadsheet
Spreadsheet
A spreadsheet is a computer application that simulates a paper accounting worksheet. It displays multiple cells usually in a two-dimensional matrix or grid consisting of rows and columns. Each cell contains alphanumeric text, numeric values or formulas...

Reactive programming
In computing, reactive programming is a programming paradigm oriented around data flows and the propagation of change. This means that it should be possible to express static or dynamic data flows with ease in the programming languages used, and that the underlying execution model will...

Callback (computer science)
In computer programming, a callback is a reference to executable code, or a piece of executable code, that is passed as an argument to other code. This allows a lower-level software layer to call a subroutine defined in a higher-level layer....

Ajax
- Mythology :* Ajax , son of Telamon, ruler of Salamis and a hero in the Trojan War, also known as "Ajax the Great"* Ajax the Lesser, son of Oileus, ruler of Locris and the leader of the Locrian contingent during the Trojan War.- People :...
, along with sharing and access-control
Access control
Access control refers to exerting control over who can interact with a resource. Often but not always, this involves an authority, who does the controlling. The resource can be a given building, group of buildings, or computer-based information system...

Haskell (programming language)
Haskell is a standardized, general-purpose purely functional programming language, with non-strict semantics and strong static typing. It is named after logician Haskell Curry. In Haskell, "a function is a first-class citizen" of the programming language. As a functional programming language, the...
