JavaScript for beginners: Learn Basics Of Programming And JavaScript FAST

About the Book

I wrote a book that will teach you the core of programming and JavaScript. After this book you will easily learn frameworks and if you want back end(Node.js).

Book starts from basic data types and goes through object oriented programming and even touches the advances topics like functional programming. At the end of the chapters there are exercises that help you solidify your knowledge.

Book is made with minimal text and maximum knowledge. There are no long pointless text. Straight at the point

I hope you enjoy it and learn something new!
