16 JavaScript Concepts JavaScript Professionals Must Know Well

July 9 Last Year

(Essential JavaScript Concepts for Modern JavaScript Development )

If you plan to work as JavaScript Professional, there are some JavaScript concepts and JavaScript-related web-development technologies that you must know well, particularly as a modern JavaScript developer. If you know the 16 concepts enumerated below very well, you have the skill necessary to build world-class modern JavaScript web applications, and you are set for the near future—0-3 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 on the homepage 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 enumerated below are neither complex nor difficult, you will get the most benefit from them if you already know at least some basic JavaScript.

These are the sixteen concepts that every modern JavaScript developer must know well:

  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 and Embrace the Future (coming soon)
  11. JavaScript Custom Events with PubSub (Published in 3 weeks—around August 2)
  12. Unit Testing Your JavaScript Applications is Essential (Published in 5 weeks—around August 14)
  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

    In which year you publish your articles? ;-)

    • Richard Bovell

      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.
