235 Free Javascript Ebooks, Tools and Resources
JavaScript is a text-based programming language used both on the client-side and server-side that allows you to make web pages interactive. Where HTML and CSS are languages that give structure and style to web pages, JavaScript gives web pages interactive elements that engage a user. Often abbreviated as JS, Javascript is also 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. It is a simple and easy-to-learn programming language as compared to other languages such as C++, Ruby, and Python. It is a high-level, interpreted language that can easily be embedded with languages like HTML. It was developed by Netscape Communications Corporation, Mozilla Foundation, and ECMA International.

For those want to learn to program, one of the biggest advantages of JavaScript is that it is all free. You don’t need to pay for anything to get started. It is used across the web development stack, both front end and backend. Google develops and usually open sources it’s own JavaScript tools. The most obvious example is AngularJS. Angular is used most prominently in Google’s DoubleClick advertising platform, but it’s also one of the most popular front end frameworks available.

This is a collection of must-have JavaScript resources. It covers free ebooks, online tutorials and references, videos, free newsletters and various other free tools as well as source codes. Suitable for those who are just starting out or seasoned experts who just want to explore further. We’ve also included some Twitter accounts of JS authors and developers, so you may want to check or follow them.
