An Introduction to JavaScript Client-Side Scripting and Object-Oriented Programming.

Our take
Based on the ratings of 642 students and a sample of their written reviews. No course pays to be reviewed.
This is a short, free introduction to client-side JavaScript. The listing shows about 1.5 hours aimed at object-oriented JavaScript and event handling, with basic HTML as the only requirement. Gautam Devaraj, a web application developer, teaches it, and the description promises downloadable source code and lab exercises. It was last updated in 2017, so expect older habits and tools such as FireBug. Treat it as a quick orientation, not a path to building real applications.
The course has 642 reviews and averages 4.2 stars. The praise is mostly about brevity. Reviewers call it simple, direct and to the point, and one says it is a good refresher on basic JS. Another says the examples are basic but good for grasping the concept. The complaints are consistent. Audio is quiet on some videos, the accent is sometimes hard to follow, and one reviewer says he moves fast without enough examples. The harshest reviewer says it stays on the surface and could be googled in ten minutes.
It costs nothing, which is exactly how one three-star reviewer frames it. As a free taster it is fine. Anyone already writing JavaScript, or wanting projects and modern syntax, should look elsewhere. Brand new learners who just want ninety minutes to see whether the language clicks get a low-risk start, then should move on to a longer course.
Pros
- Short lectures that reviewers call simple and direct, good for quick learning
- Free, with source code and lab exercises promised in the course description
- Covers object-oriented JavaScript and event handling in about 1.5 hours
- Works as a handy reference or refresher for people who know a little JS
Cons
- Audio is quiet on some videos, and a few reviewers struggled to hear the instructor
- Low-star reviews say it stays on the surface, and one reviewer found the pace too fast
- Last updated in 2017, so tools and practices are dated
Simple, direct and right to the point. A great refresher course for basic js.
Listed for all levels, but it fits beginners with basic HTML best. One reviewer found the pace too fast.

Course Description
In a prototyping language every object is an instance of a class. What that means is that objects can be defined and developed on the fly to suit a particular use, rather than having to build out specific classes to handle a specific need. This opens the door for very rapid and flexible development as well as a wide array of possible design patterns that would not be possible in more structured languages. The ability to prototype also allows seamless extension of existing classes, even built in ones.
JavaScript is interpreted by the browser and over time (most) browsers have adapted to giving power users enough freedom to look under the hood and see or even change the JavaScript that's running behind your favorite sites. Pressing F12 on most browsers will open the console which can let you talk directly to the JavaScript and explore it from a top down perspective. In addition to this, many talented developers have created their own publicly available and free tools that make working with JavaScript even easier.
Using these tools makes it very easy to debug your JavaScript too. Any error you run into can be traced back to the exact place it occurred in the browser console or in FireBug. You can place breakpoints in the page code in order to debug the code using traditional methodologies, or simply unit test the bits in the console until the part that isn't working becomes happily apparent.
While JavaScript is probably not the first language that comes to mind when talking about O.O.P. (object oriented programming), it is absolutely able to make use of Object Oriented Design Patterns and principles.
JavaScript may have had humble beginnings, but has grown astronomically over the last decade in scope and application. It is fully supported by all modern browsers and works seamlessly with HTML/DHTML, CSS3 and background services via AJAX. Take a look at its growing popularity compared to other popular languages.
