Does Google uses Haskell?

Haskell is used on a small number of internal projects in Google, for internal IT infrastructure support, and the open-source Ganeti project.

Why is Haskell not used?

The reason is quite obvious. The facilities and elegance of Haskell are very different from the needs of most mainstream programming. Haskell just isn’t the right tool for these jobs. One of the most common patterns in popular programming is runtime polymorphism.

Does Facebook still use Haskell?

At Facebook, we’re using Haskell at scale to fight spam and other types of abuse. With our Haxl framework, engineers working on spam fighting can focus on functionality while the system automatically takes advantage of the available concurrency.

Is Haskell still useful?

Haskell is a perfect choice for high-load concurrent applications, such as web backends. Maintainability. Haskell encourages using the type system to model the business domain and making the assumptions explicit. As a result, refactoring the code and adapting it to changing requirements is much easier.

Why is Haskell so popular for functional programming?

You only care what the program is to compute not how or when it is computed. This makes Haskell a more flexible and easy to use language. Haskell tends to be part of the solution for a problem, not a part of the problem itself. Functions play an important role in functional programming languages.

What are the side-effects of using Haskell?

There are no side-effects! This extends to variables as well – variables in Haskell do not vary. This may sound strange if you’re used to imperative programming (where most of the code consists of changing the “contents” of a variable), but it’s really quite natural.

What is a variable in Haskell?

A variable in Haskell is a name that is bound to some value, rather than an abstraction of some low-level concept of a memory cell like in imperative languages. When variables are thought of as short-hands for values (just like they are in mathematics), it makes perfect sense that variable updates are not allowed.

Who is Haskell Brooks Curry?

The language’s namesake, mathematician Haskell Brooks Curry, spent his career working in the area of Combinatory Logic (a notation designed to remove the necessity for variables in mathematical logic), which provided the foundation for functional programming.
