nhc98 is a bytecode compiler focusing on minimizing memory use. The York Haskell Compiler was a fork of nhc98, with the goals of being simpler, more portable and efficient, and integrating support for Hat, the Haskell tracer. It also had a JavaScript backend, allowing users to run Haskell programs in web browsers.
Elm uses an abstraction called ports to communicate with JavaScript. [25] It allows values to flow in and out of Elm programs, making it possible to communicate between Elm and JavaScript. Elm has a library called elm/html that a programmer can use to write HTML and CSS within Elm. [26] It uses a virtual DOM approach to make updates efficient. [27]
However, since the code only uses methods common to the interface Map, a self-balancing binary tree could be used by calling the constructor of the TreeMap class (which implements the subinterface SortedMap), without changing the definition of the phoneBook variable, or the rest of the code, or using other underlying data structures that ...
Haskell distinguishes function calls from infix operators syntactically, but not semantically. Function names which are composed of punctuation characters can be used as operators, as can other function names if surrounded with backticks; and operators can be used in prefix notation if surrounded with parentheses.
Yesod (Hebrew pronunciation:; Hebrew: יְסוֺד, "Foundation") is a web framework based on the programming language Haskell for productive development of type-safe, representational state transfer model based (where uniform resource locators identify resources, and Hypertext Transfer Protocol (HTTP) methods identify transitions), high performance web applications, developed by Michael ...
The Haskell library "unordered-containers" uses the same to implement persistent map and set data structures. [4] Another Haskell library "stm-containers" adapts the algorithm for use in the context of software transactional memory. [5] A Javascript HAMT library [6] based on the Clojure implementation
In Haskell syntax, ":" prepends an element to a list, tail returns a list without its first element, and zipWith uses a specified function (in this case addition) to combine corresponding elements of two lists to produce a third.
The Haskell Platform is a set of software packages, tools, and libraries that create a common platform for using and developing applications in the programming language Haskell. With the Haskell Platform, Haskell follows the same principle as Python : "Batteries included". [ 3 ]
