  2. GitHub logo lydiahallie / javascript-questions

    A long list of (advanced) JavaScript questions, and their explanations ✨

    JavaScript Questions

    I post multiple choice JavaScript questions on my Instagram stories, which I'll also post here! Last updated: June 12th

    From basic to advanced: test how well you know JavaScript, refresh your knowledge a bit, or prepare for your coding interview! 💪 🚀 I update this repo regularly with new questions. I added the answers in the collapsed sections below the questions, simply click on them to expand it. It's just for fun, good luck! ❤️

    Recommended This repo contains a collection of JavaScript code snippet based questions and answer with explanations. The repo consists of almost 150+ question and answers, the complexity of the question varies from simple to advance level. This repo is a good source to understand the concepts of JavaScript and it's working.
  3. GitHub logo getify / You-Dont-Know-JS

    A book series on JavaScript. @YDKJS on twitter.

    You Don't Know JS Yet (book series) - 2nd Edition

    This is a series of books diving deep into the core mechanisms of the JavaScript language. This is the second edition of the book series:


    To read more about the motivations and perspective behind this book series, check out the Preface.

    If you're looking for the previous first edition books, they can be found here.


    I recommend reading the second edition books in this order:

    If you're looking for the previous first edition books, they can be found here.


    As always, you'll be able to read these books online here…

    Highly Recommended You don't know JS is a free JavaScript book series by Kyle Simpson, he has done many popular tutorials on JavaScript. The books are not entry level stuff, you need good basic knowledge about JavaScript to understand the books, and mind it you cannot finish the books in a single sitting. The first edition of the book series consists of 6 books, second edition till now have two completed books. I highly recommend his books as it will give you deep knowledge about JavaScript.

    Highly Recommended This repo is about how we should style out JavaScript codes. Why we need style guides? Different programmers write code differently, each person has their own style, so it become difficult for on person to understand another person's code quickly. Style guide can be defined as the rules / standards that outline how code should be written and organized. Style guide help to keep the coding patter across a company same and help to keep the code clean and easy to understand. It will also help in debugging.

    Humorous image of software quality estimation as a count of how many expletives you shout when reading code

    Software engineering principles, from Robert C. Martin's book Clean Code adapted for JavaScript. This is not a style guide. It's a guide to producing readable, reusable, and refactorable software in JavaScript.

    Not every principle herein has to be strictly followed, and even fewer will be universally agreed upon. These are guidelines and nothing more, but they are ones codified over many years of collective experience by the authors of Clean Code.

    Our craft of software engineering is just a bit over 50 years old, and we are still learning a lot. When software architecture is as old as architecture itself, maybe then we will have harder rules to follow. For now, let these guidelines serve as a touchstone by which to assess the quality of the JavaScript…

    A complete computer science study plan to become a software engineer.

    Coding Interview University

    I originally created this as a short to-do list of study topics for becoming a software engineer but it grew to the large list you see today. After going through this study plan, I got hired as a Software Development Engineer at Amazon You probably won't have to study as much as I did. Anyway, everything you need is here.

    I studied about 8-12 hours a day, for several months. This is my story: Why I studied full-time for 8 months for a Google interview

    Please Note: You won't need to study as much as I did. I wasted a lot of time on things I didn't need to know. More info about that below. I'll help you get there without wasting your precious time.

    The items listed here will prepare you well for a technical interview at just about any software company including the giants:…

    This repo is one of the best repo to understand concepts that you need to ace your interview. It contain list of topic you need to understand to have a software development job without a CS degree. It is not JavaScript Specific, but this repo is a good resource to understand various basic topics.
