Learn JavaScript hands on in quick and easy steps
Created by: Bharath Thippireddy
Last updated September 2026
Our take
Based on the ratings of 7,659 students, a sample of their written reviews and the syllabus, as the course stood in September 2026. No course pays to be reviewed.
This free, bite-sized intro to client-side JavaScript comes from Bharath Thippireddy and packs 93 lectures into under five hours across 15 sections, moving from variables and loops through events, the DOM, the Browser Object Model, form validation, and custom objects. There are 14 quizzes and 10 assignments but no coding exercises, so students practice in their own editor rather than in-browser challenges. It suits complete beginners and web developers who know HTML but never learned JavaScript properly.
Reviewers consistently praise how simple and clear the explanations are, and one reviewer calls it a good building block class. The 4.5 rating across 7,659 reviews backs that up, with most scores landing at 4 and 5 stars. The complaints cluster around two things: a couple of reviewers, including one who left 2 stars, say parts of the content read as outdated next to current JavaScript standards, and one 3-star review notes Bharath stopped answering Q&A questions partway through.
At free, the value is hard to argue with, and the course shows a recent update even though the original went up back in 2016. It works well as a first pass before a longer, project-based JavaScript course, since it skips coding exercises and real projects in favor of short, focused lectures. Beginners wanting a clear map of the language will get what they came for. Anyone wanting to build something along the way should look elsewhere.
Pros
- Free course with 93 short lectures covering JS basics start to finish
- Goes beyond syntax into the DOM, BOM, form validation, and custom objects
- Quizzes and assignments throughout help you practice as you go
- Reviewers repeatedly call the explanations simple and easy to follow
Cons
- No coding exercises, just quizzes and assignments, so less hands-on practice
- A couple of reviewers say parts of the content feel outdated for modern JS
- One reviewer says Bharath stopped answering Q&A questions partway through
Great class. Good intro to the basic concepts and plenty of exercises to try on your own. A good building block class.
Billed as all levels, but it really suits HTML-literate beginners who have never written JavaScript before.

Course Description
This hands on JavaScript training course provides the fundamental knowledge necessary to design and develop dynamic Web pages using JavaScript. It introduces students to client-side JavaScript and how the language can be used to turn static HTML pages into dynamic, interactive Web pages.
JavaScript is the globally used client-side scripting language for the web. Most browsers support the language by default, so you can get started using JavaScript and HTML with a simple text editor and browser for testing. Client-side, programming languages make web pages dynamic without making calls to your web servers for every button clicked, character typed, or mouse moved. The JavaScript language is so popular that thousands of developers have made customised libraries that make development even easier for other programmers and web designers. If you design web pages, you'll certainly need to know JavaScript to make a custom UI (user interface).
JavaScript topics include adding JavaScript to a Webpage, use of dialogs to interact with the user and JavaScript intrinsic objects such as Date, Array and Math. Students will also be introduced to the Document Object Model (DOM), creation of functions, event handling, form validation, object creation and more.

Nice introductory course. This course helped me at work to understand a JS code and make changes. While most of reviews told me it was outdate, but this course was easy to follow and with little bit of web search I was able to do what my supervisor wanted. A little introduction with API would have helped too. Thank you for offering this course in free.
By Moises Aragon on 3/26/2021
This is an overall great program for a beginner to learn from. The lectures are thorough, quick, and re-watchable. There are command keys/shortcuts that a novice might not be familiar with that could be declared by the instructor when using them (such as [control + s] for a quick save) but all in all, this lecture is philanthropy at its finest. Thank you to all those affiliated with this website. Continue with quality videos like these and the world will be intoxicated with you all!
By Chandan kumar Shani on 6/29/2020
The instructor is great and he explains every concept in easy and concise manner. The course is design in such a good way that the videos are short less than 5 min and the sections are divided well. And the best part the course is free.

I am really happy and satisfied to get this course. I actually got it for free. Thanks a lot :) I want to build a simple project from scratch using below languages which I already know by now. HTML, CSS, JavaScript & Bootstrap So looking forward for such interesting courses for free.
By Mario Vega on 4/4/2018
This course was amazing!! It really helped me understand JavaScript fundamentals incredibly easy and efficiently. The content was very clear and to do the point. Anyone who is new to programming and wants to start with JavaScript should start with this course. It will help tremendously. It was very clear and very well taught! Thank you so much Bharath Thippireddy! You made an incredible course!

This course teaches Java Script fundamentals very nicely and this course has given me confidence and to move forward into web development , web programming. thank you Bharath sir for this wonderful course. that never made me feel Javascript is too difficult to learn. Nice and to the point explanation. I wish to enroll in other web development courses by bharath sir. :)
By Saranya V on 11/19/2017
The way of teaching is OK. The problem I felt is that the instructor is not so responsive. I have asked so many doubts in Q&A & yes,he responded to some of my doubts in the early stage of the course. But later whatever doubts I asked remained as such. No responses at all!!!!!
By Zia Hossain on 10/25/2017
Good course. It's a learn by doing method of learning JS. Although I expected a bit more explanation on issues like object, this, functions, closure. But overall I am satisfied with this course. Thanks to Bharath!!
By Ariel Gayorgor on 8/27/2017
