Write powerful, clean and maintainable JavaScript with clear, practical lessons in application architecture, package management, tools, shorthands, callbacks, classes, flow control and much more.

JavaScript: Best Practice

Preface

There’s no doubt that the JavaScript ecosystem changes fast. Not only are new tools and frameworks introduced and developed at a rapid rate, the language itself has undergone big changes with the introduction of ES2015 (aka ES6). Understandably, many articles have been written complaining about how difficult it is to learn modern JavaScript development these days.

The Anatomy of a Modern JavaScript Application

Creating a method also means writing an API — whether it’s for yourself, another developer on your team, or other developers using your project. Depending on the size, complexity, and purpose of your function, you have to think of default settings and the API of your input/output.

Clean Code with ES6 Default Parameters &amp; Property Shorthands

In this post, there’s lots of stuff to cover across a wide and wildly changing landscape. It’s also a topic that covers everyone’s favorite: The JS Framework of the Month™.

JavaScript Performance Optimization Tips: An Overview

In this chapter, we’ll dig into the best way to implement a singleton in JavaScript, looking at how this has evolved with the rise of ES6.

JavaScript Design Patterns: The Singleton

In this chapter, I’m going to take you on a tour of the various styles of JavaScript object creation, and how each builds on the others in incremental steps.

JavaScript Object Creation: Patterns and Best Practices

Modern JavaScript is evolving quickly to meet the changing needs of new frameworks and environments. Understanding how to take advantage of those changes can save you time, improve your skill set, and mark the difference between good code and great code.

Best Practices for Using Modern JavaScript Syntax

JavaScript is regularly claimed to be asynchronous . What does that mean? How does it affect development? How has the approach changed in recent years?

Flow Control in Modern JS: Callbacks to Promises to Async/Await

ES6 introduced classes to JavaScript, but they’re too simplistic for complex applications. Class fields (also referred to as class properties ) aim to deliver simpler constructors with private and static members. The proposal is currently at TC39 stage 3: candidate and could appear in ES2019 (ES10).
