Resources to Polish Your JavaScript

Alt Text
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.

It is one of the most common programming languages used today. Its popularity increased after the advent of Node.js. Brendan Eich initially wrote JavaScript though others have contributed to it throughout the years. JavaScript powers most of the websites that we see today.‍

3. Learning JavaScript Design Patterns

Design patterns are reusable solutions to commonly occurring problems in software design. They help us build upon the combined experience of many developers that came before us and ensure we structure our code in an optimized way, meeting the needs of problems we're attempting to solve.

Design patterns also provide us with a common vocabulary to describe solutions. It can be significantly simpler than describing syntax and semantics when attempting to convey a way of structuring a solution in code form to others.

This E-Book is not targeting beginners. Instead, it targets advanced and experienced developers who seek to improve their coding skills. The book is divided into 16 chapters covering common and eloquent design patterns employed while writing your code. The book also covers common jQuery coding patterns.
