Learn JavaScript

JavaScript is an interpreted multi-paradigm scripting language that forms the perfect web triad together with HTML and CSS of the front-end layer of web development.

Things To Know

What is this course about?

JavaScript is a client-side scripting language used together with HTML and CSS to build dynamic and interactive webpages. It completes the front-end development triad together with HTML and CSS and has a high demand out in the market. It has got a large supportive community with the help of which you can solve nearly any problem you face while developing programs in it.

JavaScript is a fairly easy-to-learn language as you can see from the statistics (on the right or below) and is a good choice for beginners for their first programming language as it can give them the feel of a programming flavor and yet not make things overwhelming. However its measure of ease is relative to other programming languages out there like C, C++, Java etc. These languages are quite complicated to understand and write programs in and have a low-level nature as compared to JavaScript's high-level one. So in short if you've learnt, or tried to learn any of these languages then learning JavaScript will be a piece of cake for you!

For those of you who haven't learnt any of these, the good news is that even for you JavaScript will be a piece of cake because of this course!

What will you learn in this course?

This course is aimed at making you perfect in developing JavaScript programs by teaching you how to do things and how to do them the right way. When you complete this course you will definitely feel, think and work like a real programmer and even be able to solve real word problems and create real programs on your own.

Being specific, at the end of this course you will know:

  1. JavaScript basics where to write JavaScript code, how to write it, how to use the console etc.
  2. How to work with numbers, strings (text), and booleans
  3. How to solve conditional problems using if..else statements and iterational problems using for and while loops
  4. How to work with data structures like arrays and objects
  5. How to work with functions and complex topics like closures and recursions
  6. How to work with objects and the importance of Object-Oriented Programming in general terms
  7. How to employ constructors and prototypes to emulate the behaviour of OOP classes and sub classes
  8. How to work with HTML DOM and the Events API in building page interactivity and dynamicality by querying HTML and CSS and responding to user actions like clicking a button
  9. How to use JavaScript predefined functions to calculate dimensions of elements, viewports, including or excluding padding, borders, margins, outlines etc.
  10. How to work with HTTP related stuff using JavaScript, like cookies.

Although we have given roughly a lot of information on our course, you can check out more below in the course overview and explore the details of each unit seperately.

Why should you take this course?

There are tons, or maybe even more, JavaScript courses out there on search engines and in that ton we are also a listing, but how are we different from others?

  1. We'll take you through the course in a carefully planned hierarchical manner going from extreme basics to basics, to intermediate and so on. We won't introduce concepts to you before explaining them, or if we do so (very rarely) we will surely explain them at some point in the same chapter, same unit or some other unit
  2. We will deal with complex topics like closures, prototypes and explain them to you in a clear and precise manner (where most resources lack)
  3. We will introduce you to many coding ideas and how are they being used in today's programming era, like lazy loading, ajax, image galleries etc. Some will be covered in this course while some will be added in our Tutorials.
  4. We will take small basic quizes from you, between or at the end of every unit, to test your understanding of a given concept, give comments to your scores, give answers to wrong answered questions and thus make you improve as a whole in your skills!
