I came to a bitter realization last week that most of my projects so far have been built using frameworks and a bunch of NPM packages. If someone were to ask me about closures or the event loop, I am sure they were trolling me since such things do not exist in JS land.
Thus, I decided to spend most of this month, not on building another project but making sure that I know how JavaScript actually works under the hood. I have also decided to learn some fundamental computer science topics like Data Structures and Algorithms.
I have found the following resources to be extremely helpful during this journey of improving my core JavaScript fundamentals:
1. 33 Concepts Every JavaScript Developer Should Know
With almost 40k stars, I'm sure many of you already know of this amazing repo. However, I came across it just yesterday and I'm sure there are many who will find this useful.
Taking this article as an inspiration, this repo points to well-explained articles, blog posts, and videos about each JS topic.
2. JavaScript Algorithms and Data Structures
Another amazing repo that presents JavaScript-based examples of many popular algorithms and data structures. Furthermore, each algorithm and data structure has related explanations and YouTube video links for further reading.
3. JavaScript Questions
This is an exhaustive list of example-based JavaScipt questions that will help test your core knowledge of JavaScript, refresh your knowledge a bit, or prepare for your coding interview!
Lydia, the repo owner has some thorough articles about the JS concepts on DEV, so do check those out as well!
4. You Don't Know JS
Basically a holy grail for JS developers, this book series dives deep into the core mechanisms of the JavaScript language. Kyle Simpson, the author has made all the books available for free online.
5. Clean Code JavaScript
Not necessarily interview-related, this repo is based on Robert C. Martin's book Clean Code, adapted for JavaScript. It's a guide to producing readable, reusable, and refactorable software in JavaScript.
It has tons of useful examples and can be handy for pair-programming or take-home challenges.
These are the repositories I am currently using for my JS re-education. Please comment below if you have found any other resources to be more helpful and I will add them in a different post.
Hope this was helpful. Happy coding! ๐ฉโ๐ป๐๐จโ๐ป

Great list. I would also recommend checking the follow for general coding topics that could pop up in interviews.

Thank you Iain! The repo you posted is so useful. Thanks for that. ๐
How long did it take you to cover all this
I'm nowhere near covering it. I've barely scratched the surface.
Wow I was scared one person consumed all this
Hi, Nice ๐, Just curious, can you share how you learned web development from being a Former Mechanical Engineer, How many days it took to get the
Job
?What is it with mechanical engineers converting to web development, I thought I was the only one.. turned out to be a trend lol
Very helpful article. Thanks man!
You're welcome mate! ๐
Tomorrow I will take a test and this article was very useful right now. Thank you so much.
How long did it take you to cover all this
My goal is to make sure my fundamentals are strong. So I am mostly focusing on JS and DSA concepts for this month. I'm sure it will take me a very long time to get through all this.
The more i learn, the less i know.
Excellent resources.
Thanks a lot.
nice. thanks bro
Great List!! Thanks....
