Critical Analysis of Currying in Functional Programming

An everything bagel for the brain. Substantive, layered, well-seasoned.
Summary
The article presents a critical analysis of currying in functional programming, arguing against its widespread use. It explains that currying transforms multi-parameter functions into chains of single-parameter functions, which is a fundamental concept in functional languages. However, the author contends that currying often leads to unnecessary complexity, reduced readability, and performance overhead without providing significant benefits in most practical scenarios. The article suggests that traditional multi-parameter functions are often more intuitive and efficient for real-world programming tasks.
Key quotes
· 4 pulledCurried functions are probably one of the first new things you come across if you go from an imperative language to a functional language.
In purely functional languages, the convention is to define an n-parameter function inductively by staggering the parameters.
Applying the function to argument #1 returns a function that takes parameters 2..n, which in turn can be applied to argument #2 to return a function that takes parameters 3..n, etc.
until all the arguments are given and the result is returned.
