This page provides the comparison tables of functional programming instructions between programming languages. Comparison of basic instructions of imperative paradigm is provided by the comparison of basic instructions.
Declarative programming stands in contrast to imperative programming via imperative programming languages, where control flow is specified by serial orders (imperatives). (Pure) functional and logic-based programming languages are also declarative, and constitute the major subcategories of the declarative category.
Functional programming languages are typically less efficient in their use of CPU and memory than imperative languages such as C and Pascal. [84] This is related to the fact that some mutable data structures like arrays have a very straightforward implementation using present hardware.
The table shows a comparison of functional programming languages which compares various features and designs of different functional programming languages. Name
Dataflow programming – forced recalculation of formulas when data values change (e.g. spreadsheets) Declarative programming – describes what computation should perform, without specifying detailed state changes c.f. imperative programming (functional and logic programming are major subgroups of declarative programming)
In computer science, imperative programming is a programming paradigm of software that uses statements that change a program's state.In much the same way that the imperative mood in natural languages expresses commands, an imperative program consists of commands for the computer to perform.
ML (Meta Language) is a general-purpose, high-level, functional programming language.It is known for its use of the polymorphic Hindley–Milner type system, which automatically assigns the data types of most expressions without requiring explicit type annotations (type inference), and ensures type safety; there is a formal proof that a well-typed ML program does not cause runtime type errors.

Functional programming languages tend to rely on tail call optimization and higher-order functions instead of imperative looping constructs. Many functional languages, however, are in fact impurely functional and offer imperative/procedural constructs that allow the programmer to write programs in procedural style, or in a combination of both ...
