OCaml Vs Haskell | Comparison of OCaml and Haskell
Take a look at this section to gain an understanding of Haskell and OCaml programming languages.
What is Haskell?
Haskell is a functional programming language that was first developed in the late 1980s. It is named after logician Haskell Curry and is based on the lambda calculus. Haskell is designed to be a purely functional language, meaning that functions do not have side effects and do not modify state. This makes it well-suited for parallel processing and concurrent programming. Haskell is known for its strong static type system, which helps catch errors at compile time and improve code quality. It also has a large and active community of developers who contribute to its open-source ecosystem of libraries and tools.
What is OCaml?
OCaml, short for Objective Caml, is a general-purpose functional programming language that was developed in the late 1990s. It is a descendant of the ML (Meta Language) family of programming languages and features strong static typing, type inference, and pattern matching. OCaml is known for its efficient implementation of the garbage collector, which makes it suitable for use in memory-intensive applications. It is also well-suited for concurrent programming due to its support for lightweight threads and cooperative multitasking. OCaml has an active and supportive community of users and contributors who work on its open-source ecosystem of libraries and tools.
Top 50 Differences Between Haskell and OCaml
This article explored the key differences between Haskell and OCaml, two popular functional programming languages, highlighting the Top 50 Differences Between Haskell and OCaml.
| Sr. No. | Haskell | OCaml |
|---|---|---|
| 1 | Lazy evaluation: Haskell evaluates expressions only when their results are needed. | Strict evaluation: OCaml evaluates expressions as soon as they are encountered. |
| 2 | Haskell has a stronger type system: types are checked at compile-time, preventing many runtime errors. | OCaml’s type system is also strong, but not as strict as Haskell’s. |
| 3 | Haskell uses type inference: the compiler can often determine the types of expressions without them being explicitly stated. | OCaml’s type inference is not as powerful as Haskell’s, and sometimes requires explicit type annotations. |
| 4 | Haskell has a pure functional programming model: functions cannot modify state or have side effects. | OCaml allows for imperative programming, including mutable state and side effects. |
| 5 | Haskell has a larger standard library: it includes many built-in functions and types that simplify programming. | OCaml’s standard library is smaller, but still extensive and well-documented. |
