Study Notes

Overview of Haskell

Haskell is a standardized, general-purpose programming language known for its functional programming paradigm.
It emphasizes immutability and first-class functions.

Origin of the Name

Haskell is named after Haskell Brooks Curry, an American mathematician and logician.

Main Implementation

The principal implementation of Haskell is GHC, which stands for Glasgow Haskell Compiler.

Pioneering Features

Haskell pioneered several programming language features, including:
- Lazy evaluation: computations are deferred until their results are needed.
- Type inference: the compiler can deduce types without explicit type annotations.
- Higher-order functions: functions that take other functions as arguments or return them.

Formal Specification

The last formal specification of Haskell was made in 2010.

Historical Context

The initial efforts of the Haskell working group were influenced by the programming language Miranda.

Popularity Metrics

As of May 2021, Haskell ranked 31st in popularity based on Google searches for programming tutorials.
Haskell accounted for approximately 0.18% of active users on the GitHub source code repository during the same period.
