(Essential JavaScript Concepts for Modern JavaScript Development )

If you plan to work as JavaScript Professional, you must know some JavaScript concepts and JavaScript-related web-development technologies, particularly as a modern JavaScript developer. If you know the 16 concepts enumerated below, you have the skill necessary to build world-class modern JavaScript web applications, and you are set for the near future—0 to 3 years.

I will expound on each of these sixteen concepts, and I am hopeful all of us will have become better JavaScript programmers by the time we get through all of them. I have completed most of the 16 concepts with just a few more to go, so keep reading and learning. And sign up for the newsletter to get the latest updates.

I trust you have learned JavaScript properly or you already know JavaScript enough to build a simple JavaScript-only web application. While the 16 concepts note below are neither complex nor difficult, you will understand them best if you already know at least some basic JavaScript.

The sixteen concepts that every modern JavaScript developer should know well follow:

  1. JavaScript Objects in Detail
  2. JavaScript Prototype in Plain, Detailed Language
  3. JavaScript Variable Scope and Hoisting Explained
  4. Understand JavaScript Closures With Ease
  5. Understand JavaScript Callback (Higher-Order) Functions
  6. Understand JavaScript’s “this” With Clarity, and Master It
  7. JavaScript’s Apply, Call, and Bind Methods are Essential
  8. Learn HTML5, CSS3, and Responsive WebSite Design
  9. Object Oriented JavaScript (OOP in JavaScript)
  10. Learn Node.js Completely and With Confidence Or Learn Meteor.js Properly
  11. JavaScript Custom Events with PubSub (coming soon)
  12. Unit Testing Your JavaScript Applications is Essential
  13. DOM (Document Object Model) and BOM (Browser Object Model)
  14. ECMAScript 3 and 5
  15. The Best JavaScript Front-end Frameworks You Should be Using
  16. Preventing and Handling JavaScript Errors and Debugging Your Code
  17. BONUS: JavaScript Design Patterns that Every JavaScript Developer Should Know (coming soon)

    In which year you publish your articles? 😉

    • Richard Bovell (Author)

      Dieter, I had to chuckle when I read your comment, because you are correct. I had not been sticking to my own schedule, and it probably seems like those dates for upcoming posts were for another year :).

      I uploaded 2 new posts within the last 2 days and I plan to add 2 more today.

  31. Sharon

    The posts are very useful. Can you please finish the remaining topics?

  32. Shesh

    Hi Richard,

    You have absolutely the best tutorials on the internet for those who are confused between the various styles of OOP. Very streamlined and ordered – and that is difficult for javascript.

    Node.js has evoked special interest towards javascript as a go-to language for mobile-web.

    The best part is that you have cared to correct the mistakes and the comments are educative too, they tell me where mistakes can happen (though various tools are making it easier for the developer to detect errors :)).

    Do you have any tutorials on Javascript using jQuery styling on your website?. I could not locate them.

    Thanks.

  33. Dwayne

    I’m catching pretty late, but it seems these concepts are stilly very relevant, its a very unique site.
    Thanks

  34. Wasim Ghumro

    This is a great resource and bookmark worthy. Thank you.
