About JavaScript (Wiki):
JavaScript often abbreviated as JS, is a programming language that conforms to the ECMAScript specification. JavaScript is high-level, often just-in-time compiled, and multi-paradigm. It has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions.
Alongside HTML and CSS, JavaScript is one of the core technologies of the World Wide Web. JavaScript enables interactive web pages and is an essential part of web applications. The vast majority of websites use it for client-side page behavior, and all major web browsers have a dedicated JavaScript engine to execute it.
As a multi-paradigm language, JavaScript supports event-driven, functional, and imperative programming styles. It has application programming interfaces (APIs) for working with text, dates, regular expressions, standard data structures, and the Document Object Model (DOM).

in short span basics got clear and the instructor has smooth delivery. there may be less instructors out there like him who gives precise basic knowledge and do not waste time

Very good introduction to JavaScript. Moved at the perfect pace, not too much information but enough to really feel like you have a good basic understanding of the key concepts. The only problem is that the instructor's pronunciation is quite difficult to understand for a non-Indian English speaker. But it's worth the extra effort to understand as it's a great course. Thank you!

In just under 2 hours of learning thru this course, I now know key Javascript concepts! The instructor smoothly takes you thru the concepts in Javascript in a simplified manner for students to grasp knowledge in the subject area. It is not too detailed, nor it is at a cursory level. Just right to get yourselves familiarized with the language what otherwise may seem unknown to many of us.

Instructions were easy to follow but would be highly appreciated if in the first lecture, the instructor indicates that I need to download node application in order to run .js file

guy teaches good but didnt tell us how to install the neccassary files (i think) some people can use notepad for these things and for the console they can use the browsers inspect element>console as console but great experience
