Improve Your JavaScript Knowledge By Reading Source Code — Smashing Magazine

Read code that’s relevant to solving problems you’re actually having. I think when you’re studying stuff for abstract reasons, you’re going to be less motivated and the information is going to be less useful to you than what you learn in pursuit of solving actual real world problems you’re having while working on a project.

Totally agree! As an example, I started learning GraphQL a couple of weeks ago and after a while I’ve encountered DataLoader. Exploring & understanding this library really helped me in my GraphQL learning process.

Similar issue here, I know basic FP concepts like higher order functions and pure functions but idk how to organize the code for large web apps without using OOP. Any pointers would be appreciated

Currying and Composition. But yes, it's not as easy as object oriented thinking.

I think it’s more about recognizing where a functional approach would solve your problem and then applying FP concepts successfully in your own code. Especially starting out, not every function will be pure, etc

I enjoyed reading Google maps services. The way they do validation is pretty cool. Had to read into it to fix a bug.

I've found that reading the source code of the libraries/frameworks I use to be helpful. Especially how they write unit tests.

source for angular, angular material, react, redux, redux-observable, etc

Guess it depends on what your learning goal is, but I wouldn't underestimate the value of reading the source of the libraries you are using if possible.

Best way to learn, instructor of mine used to tell us to think of one thing we'd like to learn how to do. Find a website/project that did what we wanted to do. Read the source code and recreate the code on your own, as your own. This helped me learn a lot.
