Shorter way

const sum = a => b => c => a+b+c

This concept is used in forward ref in react

Hi Bro. Nice to meet you again. Why don't you implement the recursive function?

[krishnachaitanya]

Everyone asks the question but rarely uses it 😂

[simon___kov]

Why not using rest parameter to free up your stack? Calling recursive here is unneccessary, since its more bloat in ram.

1. Reusability – Curried functions allow you to reuse partial functions by supplying some arguments beforehand, reducing code duplication.


2. Code Readability & Maintainability – By breaking functions into smaller, modular pieces, currying makes code easier to read and maintain.


3. Function Composition – Currying simplifies function composition, enabling the creation of more complex functions from smaller, reusable ones.


4. Avoids Repetition – Since partial application is possible, you don’t need to pass the same arguments repeatedly.


5. Enhances Functional Programming – Currying is a core concept in functional programming, enabling a more declarative and less imperative coding style.


6. Better Abstraction – It allows developers to abstract away unnecessary details, leading to cleaner and more expressive code.


7. Useful in Event Handling – In JavaScript and other languages, currying can be useful in event-driven programming where handlers require specific arguments.

That's ok but what is the purpose of this function ? Do we really use this kind of functions in the production?

[Itsnewstyle]

Concept is called Currying...please explain why to use this?

[esportsnexus]

You should be using function curry. I'll reject you if you'll write such crap.
