What is Currying? - Coding Interview Prep

In JavaScript, currying is the process of breaking down a function that takes multiple arguments into a series of functions that each take a single argument. This allows you to create a new function by partially applying the arguments to the original function, so that you can call it later with the remaining arguments.

Your kid understood all of it.

[@JesseWeigel]

Lol, he was home sick from school and wanted to see what I did for work.

[@alish2001]

Your kid in the back is priceless haha

One of the clearest explanations of currying I've ever seen.

[@JesseWeigel]

Thanks! It was always a confusing concept for me.

[@joshuapasaba1961]

Thanks for the video. I finally understood currying using your videogame analogy. At first it wasn't clear why would I bother saving a half baked function to use later but working with the analogy, I realized that I can perform multiple evaluations of a function while keeping one variable constant. Kind of like a save point, I can start at a certain point and try do different actions from there.

thank you so much for explaining currying

[@RupluttajaGames]

Currying is when you write code like a pajeet; the examples are top notch.

[@thydevdom]

Best explanation and reason for use case

[@JesseWeigel]

Thanks!

Man, I came here to learn how to cook a mean curry. But I'm leaving being able to pass a Senior Software Engineer interview question. I'm applying for jobs now.

[@persiansatan]

so it's basically the decorator design pattern?

[@JesseWeigel]

AFAIK currying used to implement the decorator pattern in a functional way.

3:19 How can we call withTitle with one parameter when it requires two. I feel that its function definition only needs title because Component is a class imported from React

[@JesseWeigel]

I think you are correct

[@sunilchaudhary1206]

That's really nice one i knew i have been using this in vanilla js coding but didn't knew what it was called 🙈

[@LBCreateSpace]

Thank you so much. Crystal clear

[@kishDoesThings]

amazing video and excellent usage

[@JesseWeigel]

Thank you!

[@recursivethinking]

Great explanation!

[@JesseWeigel]

Thanks!
