Javascript Snippets
Secret Code Snippets used by Powerful Developers to create Innovative Apps
About the Book
This book is for anyone with a basic working understanding of JS.
It covers 9 chapters with innovative and interesting ways of solving common situations when working with Arrays, Objects, NodeJS, Functions, Browser and more.
The idea is for you to also use some of the snippets as plug and play functions in your projects.
Why learn in this way ?
Javascript is one of the most versatile and powerful programming languages, learning the basics and using libraries like Jquery is really easy, however most of the time the solutions to the problems we face might be coded in a simpler and more efficient way.
This book serves as a reference guide providing code snippets written in an efficient way, by studying each of them, and even customizing some of the snippets to better suit your project you will get in the habit of writing code like a god.
If you really want to develop a mindset which allows you to code in a precise and fast way, then there’s no escape. You must understand the idea behind each snippet and implement it on a project, by having the experience and solving all the challenges you face you will become a successful developer.
