Language structures related to functions

Features

First-Class Functions (JavaScript, Python, Haskell, Scala, Swift) Functions are treated like values that can be passed, returned, or assigned.

Closures (JavaScript, Python, Rust, Swift) Functions that capture and use variables from their defining scope.

Higher-Order Functions (Haskell, Scala, JavaScript, Python) Functions that take other functions as parameters or return them.

Currying (Haskell, Scala, JavaScript) Transforming a function of multiple arguments into a sequence of unary functions.

Partial Application (Haskell, Scala, Python) Pre-filling some function arguments to create specialized functions.

Default Arguments (Python, C++, JavaScript, Kotlin) Function parameters that take a default value if not provided.

Variadic Functions (C, C++, Python, JavaScript) Functions that accept a variable number of arguments.

Tail Recursion (Scheme, Haskell, Scala, Elixir) Optimization technique for recursive functions that reuse stack frames.

Anonymous Functions / Lambdas (Python, JavaScript, C++, Java, Swift) Functions without a name, often used for short operations.
