Functional Programming and JavaScript ES6+ Applications

I tried to code using the functional library by applying the concepts learned from the previous lecture, but the auxiliary function became longer and the imperative code was simply moved to the auxiliary function. I couldn't shake the feeling that the imperative code was just changed to a function with control statements in Go. After listening to this lecture, I think it was a lecture that filled in the 2% that was lacking when I just listened to the previous lecture and blindly rushed into coding, such as looking at map, filter, and reduce from a different perspective, wrapping iterables/iterators with the above functions, safe function composition through monads, and techniques for extracting highly reusable functions and abstracting them for continued use. I haven't fully digested this lecture yet, but I will study it by listening to it over and over again. Thank you for the great lecture.

"The best lecture that makes you look forward to the next lecture" When you first listen to it, you are full of questions like, what is this? How does it work? But as you savor each piece of code, you will fall in love with the charm of the JavaScript language and you will be completely absorbed in the well-organized lecture and delivery. I am eagerly waiting for the instructor to have more time to create the next lecture. (I hope the next lecture will include a lecture where you create an actual project together!)

Really attractive functional programming..!! It's a really good lecture! I recommend it a hundred times!

It was good to see a practical application case of functional JavaScript. I was able to feel functional programming more concretely by seeing how situations that need to be solved in practice are solved with functional programming and easy-to-read code. In the next lecture, it would be good to teach how to design and manage dependencies when creating specific services and applications using functional programming. Thank you for the great lecture :)

I ran all the way to the end in one breath. It was really informative and fun. I think I need to practice to apply it to my work, but I think I can apply it little by little like I did when I first created the addMaker function. Thank you. I hope you will continue to give good lectures! Thank you for your hard work!

I studied Indong's functional programming lecture and applied it to my work, and I'll share with you the magical benefits I felt :) 1. As I coded around keywords and conventions such as iterable and functional, I was able to naturally achieve the effect of aligning coding conventions when collaborating with my team members, and as a result, I was able to obtain consistent codes as results. I didn't realize it when I was coding like crazy, but I think I ended up with code results with maximized reusability! 2. Related to number 1, but since it became easier for team members to read each other's codes, it became much easier to detect logical errors when conducting code inspections. 3. When I coded in imperative form, I would stutter a lot when reading code again after just 1~2 weeks, but now I feel less reluctant and lazy when reading old codes! 4. Coding became fun :)

This lecture was also quite good. However, in my case, I took the previous lecture 4 months ago and applied it to my work. So, although not everyone, there were many parts of the first half of the lecture that I was already using. This part was a bit disappointing. Perhaps, if this lecture had come out sooner, the time wasted in my work would have been reduced a lot. The biggest gain for me this time is the content from 'Handling Time Iterably'. I am looking forward to it because I got a lot of new ideas that I can use in my work, so it will be of great help. Thank you again for the great lecture.

A review of the advanced course~ I thought the advanced course would be harder than the basic course, but if you listen to it with the effort to understand the more abstract codes in the basic course, I think functional coding at the app level is easier and more fun.
